emission's robbing HP ...

Where could i find a general diagram of all emissions relay's that i could disconnect to free up a few extra horses, i was told here now with the emissions law's "least in pa" they must be usable, not connected ... its all visual inspection ... somewhere to start anyway ...

This is a 90s car, not a 70s one. I doubt you'd get 2 more HP by dissing every single emissions component.

The real payoff is in chip programming; not unbolting easy-to-get-to and obvious things in the engine compartment that "don't look good". You can probably get 15 times the results by chip tuning, that you can get by hacking.

Bottom line: leave the physical stuff alone, and learn to re-program the control system.

Id leave all that alone. If you want to free up some power, get a full exaust with a high flow cat or cats.

Chances are you will make it run worse and lose power/driveability by eliminating the emissions systems.

i took all of the emissions crap from both my 88 and 92 tbi cars and i`ve never had a single problem. i think it did free up a little power. not much but alittle.
