How big of a difference did you notice after Pulley/Tune upgrade on '11-'12?

[EvilSnake]

I am interested to hear how big of a difference 2010-2012 owners noticed after doing a pulley and tune upgrade on their cars. I don't care if its a Lund, VMP or whoever tune. Assuming the gains are somewhere around 60 or 70hp, I'd like to know how evident the change in power is.

Of course owners of the 2007-2009 GT500's will have noticed a bigger difference due to the fact that their pulley/tune upgrade achieves more power so their opinions are not valid on this topic. Sorry! :beer:

Very noticable..around 50-60rwhp. Call Van and get the 2.5" pulley with Lund tune and the rwhp will be north of that.

A very noticable gain. I went from 476 471 to 530 514 with pulley, tune, and xpipe.
The car pulls really hard through the entire rpm range, great bang for your buck.

Here is my dyno from stock, to upper/idler and custom tune.

Can't wait to see what I make with my new setup in a week or two. Oh dyno fun

I never had my '11 dyno'd but there was a very very noticeable difference. Going from 9lbs of boost stock, to 13 or 14lbs, you can really feel it in your stomach when it's accelerating. It's 100% worth the money. I just ordered a 2.5" pulley for my '12. It's addicting.

I have a 2.5" and VMP tune sitting on the table... just waiting for some decent weather to do the install. Thanx for the responses... I was just wondering because so many people say that its a night and day change for the car but I had to wonder if that was because they had a 07-09 GT500 and the gains are a fair amount more than the '10-'12.

Nice power gains but 13.11 A/F is a pretty aggressive tune.

Sorry for the newb question, but what is the average cost of a pulley and tune?

I did the VMP 2.59 on my 2010.....don't know what the pre-mod #'s were, but with pulley, non-aggressive tune and headers I ended up with 552/556. To me it was an absolute world of difference - couldn't be happier.

That's boost

I did the tune first and noticed a difference in top end pull. Then did the pulley and the car had more low end grunt, broke the tires loose easier. It will be a noticable difference especially for the money but it won't make you crap your pants. That will take a KB or whipple.
