I would say no. Especially with a Diablo tune.
So you would like me to get a baseline and then push the 93 tune and last some custom changes to the 93 tune. We are looking at 4 hours on a dyno. I'll check the current hour rate and get back. All this would be after X-mas.Forgot to mention,,, you will be surprised the HP gains by doing the dyno tune and tuner acquisition and the use of one of the canned tunes it provides if you just have it dynoed without a professional tune to keep the expense down. I would say that you will get more from doing it that way then by way of upgrading in the way your question implies.
The 93 tune feels good in second gear. I'll pick up an R2C intake, BBK header and that will do me. Its my Wife's car
Me: CAI, SRT shorties, Corsa catback, custom dynotune, 180 tstat, 85mm TB got me almost 30 rwhp and 40-45 rwtq. True HP gains are not cheap and what you are listing might get you 5 rwhp, however, the right CAI will help make your car sound better and you will notice a little better response in the butt dyno.CAI+Tune+180 Tstat=25 to 30 RWHP, Yes or No? Thanks
