So I got my car tuned and dynoed with my new goodies.

Stage 2 Fox Lake heads
CMS 2.5 blower cams
2.87 pulley
Full exhaust

Car made 427 rwhp and 371 rwtq.

My tuner is boggled by the low numbers, as am I. Everything looks good on his charts but the car is only making 10 lbs of boost. He says its almost like the cams in there are N/A. The idle doesn't sound like a blower cam idle to him either. Let the discussion commence!

You need nawzzzz

But no really that seems really low. What kind off boost should that pulley be making?

He should be closer to 14-16 I think.... IIRC...

Tuner said 13ish, I am intercooled.

bopiela

13. that would give some nice power... i wish i could help but im still new on the tuning and FI part of stuff. do you have the fuel capabilities for more? ur pump and injectors i guess?

either way, good luck man. hope it figures itself out!

i was running 14lbs with no heads or cams on my 2.95 pulley. are you running an 8 rib setup? could your belt be slipping?

99 GT vert

could you have a leak some were in the piping?? intercooler have a crack?

jvog

Thanks, and yea my fuel system should be able to support it.

jvog

Well heads and cams should lower the boost number because they are less restrictive, and no belt slip and its a 6 rib setup.

The boost numbers on the dyno pulls are way too consistent to be a leak I think.

You still got it down at Matt's?
