MY 06 was tunned yesterday. It has the high boost-10 psi Kraftwerks sc, IDs 1000 and FlasPro. Other than the Fujitsobo exhaust, its stock. The tunner/installer says its working fine but the numbers are lousy. It made 337hp and 214 torque... He blames the 92 degree outside temperature.. What do you guys think ? Any help greatly appreciated.

 

Are the numbers corrected? I wouldn't blame the temps if they are.

 

yep, correction applied. The blower put 9.5 psi...

 

More importantly, what did you baseline? If this dyno reads low, this could be perfectly normal.

 

The guy in charge did 3 other Kraftwerks and all made very consistent numbers, like 370s hp, on the same dyno. The only difference was that mine got tuned in a hot and humid room.

 

stock CAT ? Maybe a TP or HFC would help, I think that hurts any FI. Get it retuned on a cool day to be sure.

 

It looks like he tuned it way too rich. Do you have a flashpro datalog from the dyno pulls? If so, I'd check the AF value and knock counts.

 

You need a long tube header & a cold air intake to bring out those gains. Did he tune the low cam first for max power, then high cam 2nd to get maximum mid-range potential (by setting a proper Vtec point)?

What is the i.d. on the exhaust? If it's less then 2.75, there's another issue.

 

Thanks everybody . The car is stock, other than a Fujitsobo exhaust, I think its dual 60 mm. Several folks here are putting 370s hp and 240 torque on stock Ap2 s while others making 380s and 250s with some bolt ons. Mine is missing about 40 lb/ft of torque, so I suspect that something is wrong... I will try to get those details. I dont know to much about tuning but the exhaust smell rich ...

 

Definitely need a test pipe or high flow cat. Your catalytic is one of, if not the most restrictive part on your car that's holding back potential power. I'm currently running with just a Berk Test Pipe and Greddy SE dual with Toda-tune on FlashPro and it's a WORLD of a difference.
