i have a question, i recently purchased a 99 gtp had a few things done to it ie headers high flow cats 3in down pipe u bend delete and a 180 thermostat, i am just wondering how i can tell if it has a pcm, i dont know what stock gtps do but when i shut my car off the fans run still kind of like a turbo timer?? i have had a turbo talon before and installed a turbo timer and it did that, is there anything else i could check to be sure? and another question, i made a cai, 3.5 in piping and k and n cone filter, i know it sounds alot better but is it helping? gonna make an air box for it at work but just trying to get some opinions on the subject....thsnks
 


it has a PCM then. stock cars dont have a 2 minute fan run after the car is turned off.

air boxes are stupid, but you should have gone with 4" piping instead. the bigger the better.
 
^^What that guy said.

Get a custom tune. There is probably someone close to you that can do it. Then get a smaller pulley since you have headers...it'll make a whole new car...probably a 3.4" would be a good bet ;)
 
yah i really want to but im scared of kR......dont wanna blow my engine....and does anyone know of anybody who could tune it in michigan?
