Hello Everyone this is my first post, I have recently built a Ls1 Engine for a 2001 Trans Am and i need some information as to which HP tuner to buy. The engine is heavly moddified with Cam, Heads, LongTube Headers (No Cats) And Changed From 28# injectors to 42# injectors i will be learning to tune this engine by myself. I was reading that the HP VCM Suite is good for slightly Moddified engines and that the HP VCM Suite Pro is better for highly moddified engines. Which should i be buying. Thank You for any and all information on this topic.
