Re: ?? First, best, most cost effective mod??
Steve,
I did pretty much the same thing with exception to the new T.B. I went with the larger fuel injectors, a N.W. CAI, Magna flow cat back system, a TVT tune/ Eurocharge and the sprint booster. I will tell you that it became a totally different car. Hoping to have a ball this week end at the Dragon.
Good luck.
