what other advice do you need than tune it?

All stock...........lol.

No doubt. What did you expect? You have an s/c, right? If its running so rich, kick@!#$ some air down its throat.

That was actually the area my car was running on stock GM N/A tune. I used HPT and leaned it out.



FU Tuning

alright i just wanted to make sure there was no other problems but it gets tuned the 1st . i thought it would lean out more with the ported head instead of run rich



8 psi with m62 and IAT under 100

its running alot slower than before to could this be because the need of the tune?



8 psi with m62 and IAT under 100

you sure its running slower or just moved the powerband so differently you think its slower?

and yes... you need a tune.

the ported head no doubtingly has meant a loss in torque though. pat ported it for a supercharged application. and with your addition of header and exhaust... yep. your probably feeling the loss of torque.

my car is slow as dirt off the line man, no torque whatsoever. yours is probably doing the same.



I'm tired of wasting my time... now I'm breakin' free.

mine gets a good jump for like a second and dies out
