u7194
00' trans am ws6
hi i installed a cold air intake slp +knn since then i feel like the power is there but the torc is not ... i was thinking since theirs more air coming in.. there needs to be more fuel.. so i richen the fuel by 10% at wot but still feels like lagging power any help would be greatly appreciated

have you tried logging your fuel trims?

also, to be honest, it sounds like you have a minute vacuum leak so check all the sealed areas you screwed with when you installed it.

my fuel trims are set no vacuum leak still do you think its my fuel pressure

a U7194 for a 2000 Trans Am?????

did you mean a U7198 ???

yeah u7198 sorry ... i messed with my power enrichment i leaned 2k .4k by 10% and same for 4k .7k..... i noticed when i hit wot at 2k to about 4k not so much power but after 4k to 7k crazy power..... what could i do to get that to run better

and my rear 02 s are coming on i have stock exhaust not bringing up a engine light but shows codes on device

clear the codes and do some logging according to this link

making blind fuel changes can be harmful to an engine.

Did you lean it out based on a wideband?
That seems like a lot of fuel to pull...especially after you increased airflow with a CAI, my guess would have been to add fuel?

ok i didnt have a data cable but i just orderd 1 .. i also put my fuel back to richer mix in the 2k to 4k and noticed a better run ....
1 question when i get my data cable will that tell me wat changes to make on my tuner? i just dont want to go on a dyno
