I am going with the tvt 265 package and adding the 74mm TB to the package, and shopping for the cheapest deal on the sprint booster. TVT 265 is $1450.00, and the Throttle body is $250. I am also getting the back cats cut today, as a friend will do it for nothing. I hope this gets me in the vicinity of my G35 as far as performance. I will post after all is done. It will probably be over a month to get it in and send off ECU for tune. I can hardly wait to bolt on 50 hp. Thanks for the direction and tips. STEVE T
