Hey guys
I work at GM dealer and had the chance to take my car out with an OBD while getting coffees![]()
Warmed my car up and put it in first gear with performance shift on. Went WOT and got about 4* of KR. I would assume 5* if i had let it go longer but there were cars in front.
I only have a FWI and TR5 plugs with resonator removed so i would have to say that's pretty good no? I have a front Plog and 3in downpipe with cat coming tomorrow so i'm thinking after that it will all clear up.
What do you guys think is to much? i know stock GTP's have KR but how much? thanks!
car is a 99 GTP
