Wow, those are some great gains!

Is that baseline with the Akra and then tuned, or baseline with a stock vs. tuned Akra? I'd be really interested to see the actual curves.

Wow those are sweet numbers...

Doesn't hurt that the exhaust is the sexiest looking/sounding. (imho)

Baseline with akra and then tuned.

I didn't have enough $ for a stock pull. :(

If i can scan the curves I'll post them up.

Basically the tuned curve has gains everywhere except @ 2k rpm. ^^"

thats awesome, i wonder my full akra will perform? where in socal did you get it tuned? how much did this place charge if you dont mind me asking? ill be putting a pc3 in next week and hopefully get it mapped as well.

Mach1 in Newport Beach. They ask about $350. Buy your own O2 eliminator kit from dynojet because they'll charge you $20 if you don't. Talk to Jim.

How was it tuned: you have a PCIII installed.
With a slip-on, PCIII and a BMC filter that's about what I'd expect. You'll probably see about 111-113 rwhp with a full system. Post the charts and tell us about the run conditions.

Otherwise there's no change your bike gained 7-9 hp with just a slip on. 3-4 would be more likely.

AZN you got the full hex akra? I finally got a chance to ride mine, and it was at a track day at Barber...man what a difference, it felt like a new bike...

Glad the bike runs good now but its not really known what gains the pipe made then cuz he never got a stock run. Was just good mapping by the tuner.

For all we know the stock bike could of made 110 hp on that dyno - then went down to 98 hp after the pipe instalation and no map- then made 107 hp after tuning. Until then you never know what the pipe made

HP aside, the feel is definately better. More responsive and way more torque. I can't keep the front wheel down like i used to. I need to eat more.

True but i've seen stock runs on the 05/06 rr and they're usually around 100-103. Either way i'm happy with the tuning.

Friend,

having a few more ponies and 5 ft lbs more torque will not turn your bike into an RCV...if you can't keep the front wheel down you better check your rear shock and make sure it still works!

Yes, I understand it takes a pc3 to tune but my point was from my understanding you can't get the proper A/f ratio with the catalytic converter intact. You either had to get them out some how or go to a full system. The cats won't allow you to measure the values correctly to get it properly tuned. It makes sense to me but I could be wrong.

Where's birdman when you need him???????

Uncle P, my response was to the fellow's post. I agree that your point is a valid one. For that matter, he would have (or at least should have) had his PAIR valve disconnected in order to obtain correct a/f readings (My bike read 3.5 % rich with the PAIR intact). He probably gained 3-5 hp, the change is likely result of differing conditions and who knows what that "baseline" actually is...

No but it does give 1st gear the ability to pick me way up to 12o'c instead of 1 inch during WOT. That's all I meant. I'm a small guy, and I really cannot keep the front wheel down when I WOT 1st. Sue me.



I think some of you are reading wayy to deep into what i'm referring to as the 'baseline'.

It's the pull prior to tuning. Nothing more. Who cares? I don't, I just thought it showed the skill of the tuner, and I'm happy with it.

The 'change in conditions' is what... 2 degrees ambient temperature? Seems to be the running joke of all bike forums to have a pessimistic crowd at every tune post.

I could care less about hp/torque gain. The best improvement is how it feels afterwards with response, and it's definately a world of difference from stock. And no matter how many people say "it's only 1-2 hp, 2-3, blah blah, not goin to make you feel like rc51 stfu" it does feel like more power to me, and from my observations and the dyno results it definately has introduced changes to my riding style.

Just for my own knowledge, why does a Cat conv impede tuning? As far as I was aware it's a measurement at the exhaust of the leftover compounds from burning fuel... if you have a stoic mixture you should have near perfect exhaust etc.

so you gained how many h.p from just mapping? LOL I can't see a graph, but that sounds like BS to me, but anyway............... according to DJ, the Cat does not upset the air/fuel mix as the CAT doesn't alter 02 at all, it converts or changes etc, other gasses........................ BUT, while in theory that works, whenyou are mapping the bike, and you have the sensor down the pie, I have found that , with Tuning Link, by the time the exhaust gas gets through the CAT and through the sensor hose and into the box and to th sensor, you are always tuning or changing values at 1000rpm or so behind, if that makes sense.............. there's too much lag between when the bike is at say, 8000rpm, and when the sensor gets to read that and change values, coz with tuning link, you are only passing through those rpms under load. I have done maps back to back with and without CATs and they are different, regardless of whetehr the CAT alters the air/fuel ratio or not, so I gut them every time.

as for not having the $'s for a stock run, what the? Surely they'd WANT to have a stock run, so they can see the gains....................... with any pipe and/or mapping I do, I always do a stock run where I can, at NO CHARGE to show the guy what he's getting. That's wierd. Anyway, glad you're happy, that's all that matters.

That's wierd. Anyway, glad you're happy, that's all that matters.

Yes, no $ for a stock run. I installed the pipe myself. Why would I pay for a stock run, then pay for them to install a slipon... then pay for tuning after the fact? I've seen 05/06 stock results and they're usually between 101-104... I can assume my bike would be in the same area. Why is 8 hp from tuning to aftermarket parts unbelievable?

Condiscend all you want, I'm just reporting what's on the dyno readout. What do you want me to say? I hate trolls.

If you really are a professional shop I too would expect a stock readout if you're goin to be gouging people for your labor... Good for you. I'm just the type that figures I wouldn't want to pay you for that labor. Why would I pay you $70/hr to pull some screws, scratch bodywork, and fail to torque anything right? I don't. That's why I say I don't have enough $. How much do you charge your patrons for your "service"? I only pay for what I cannot do myself.

The cat conv shouldn't alter A/F ratios... it's not even goin to alter the measurable leftover reactants from combustion... So why wouldn't you map the bike according to the components that are always goin to be on the bike? That's like saying "the air filter alters the A/F ratio so I just took it out...". Tuning should be done having the components you're using left on the vehicle. Do they take the CatConv off cars when they tune? I've never heard it. Everyone gives advice like they're the foremost authority on a topic... In the end I'll trust my mech.

So done with this board.

whoah there matey. LOL wasn't trolling at all. Just asking and stating some FACTS. 8h.p is what you would expect from the pipe AND mapping, not just mapping, that is why I asked. As for the $'s for the runs, I don't gauge people for the money for stock runs, if they get a pipe from me and I am mapping it for them, I'd put the pipe on and do the runs for FREE. yeah, I'm such a prik aren't I. hahahaha

and the Cat does NOT have any effect on HOW the bike runs, so what you said about the Cat being there and equating that to an air filter is complete rubbish, and in saying what you are, you may as well leave the Pair hose working to map it too then? Coz hey, the bike runs with it working. hahaha But hey, you trust who ya want, but if you trust people that show you 8h.p JUST from mapping your 600, it lies with the wrong people. LOL Have fun

I should have also said though, that 98 from a bike with a pipe, is low (if we use your theory of 100-104 stock) and so, if the map that was in the pc to begin with was bad enough to give a low reading to begin with, then, yes, you can gain 8h.p, coz the map you are running initially is losing power, from no map at all (I see that alot) and so, you GAIN 8h.p............... was the bike run with a ZERO map, or the map that came in the PC? That will let you see a lil more of what you actually gained and why, but anyway, not having a go at you or saying your full of crap, just saying.
