do you have a android phone? download the Torque app. the 5$ one, and add the extra GM parameters for KR monitoring.

and the NOS brand octane booster is pretty legit with MMT's for boosting octane. im 0* KR when i run it and i get 1*kr without

race gas is the better choice obviously.


and oxfire, thats the dumbest posts ive seen you do since being here. how can you say race gas wont take away KR? thats what it does. lol higher octane = less knock
