i got a 99 gtp its got headers high flow cat cat back 1.7 roller rockers and cai. how many horses do you think i could get and is there anywhere near abilene kansas i could get it dynoed?. i might trade it for a stang but the guy wants to know numbers so if i could get a rough estimate that'd be nice. tryin to get away from grand prixs cuz i almost got in trouble with the cops and now my car is marked.
 


I have not personally had mine dynoed... But stock they make 200whp and yours dont have a lot of mods..What pulley are you running?
 




I'm going to guess 235whp. Running too small of a pulley for that setup and the custom tune probably does have a lot of timing pulled to keep it from seeing any KR.
 


well ****..if i could trade it off i wont mess with it...if i cant i guess ill put enough in it to out run the cops...its just money right?
