I have a 05 auto/vert, I will be buying a xcal this weekend andI was wondering what kind of increase in performance I will get. Other than the tune I am stock.

 

a noticeable one. don't get overexcited and think its gonna feel like a GT or something but it will definately feel like a high performance sixer. u can make the most of it now or down the road with a new intake. RWHP gains average about 15-20 depending on the intake.

 

It helpsALOT with the auto trans.Gets rid of that lag on down shifts when you nail it. VMP tuning has a good deal on the Xcal and a $99.00 intake.Bought one last month and love it.Got the 87 mileage tune and highway mileage increased from 24 mpg to 29 mpg! 87 performance tune is FUN.Will be checking the 93 perf.tune soon.

 

I dont mean to hijack the thread but does anyon know if I have to send me tuner back to the shop to get it retuned or do they send them via the internet and I download it off the computer?
