So not trying hijack the thread because it goes along with the question.....with my current setup I hit 500hp as well and the next upgrade is going to be a compound setup.
here is my question about a turbo upgrade.....Does the bigger the turbo mean more air and more back pressure? And if so does that mean that it will help with the "Black cloud"?
I love my truck and love my tune I just wish I could get rid of some of the cloud...that way no one would know that I just jumped on it to make it thru the light if you know what I mean.....lol
