i just recently began to mod my cobalt(just finishing up on my intake, and ive had a single chamber flowmaster for months) and i was wondering what what mods i should start with and when a tune would be needed. no one i know drives a cobalt so i cant ask them and i figured this community would be the best place i know to ask.
I've done some reading and what I have come across is that with the 2.4 TB i will need a tune, which I've seen Trifecta thrown out there a lot. I had been looking at the 2.4 manifold as my next mod and but i want to get the TB as well. Any advice on the tuning aspect?
