I just wanted to point out my experience with Justin at VMP. I ordered my tunes on Tuesday, and received them today in my email. Justin has been very helpful through the whole process. My set up is the AF1 3.5 and true dual exhaust, plus 33in tires. I haven't gotten to load any of the tunes yet, because my son is sick so i'm at home with him. I currently have tune from troyer which was dyno tuned back in 2007. I figured I'd try some other tunes out, but wasn't sure if anyone can tune for the AF1 3.5, since this seems to be a troyer special. Justin informed me he could make tunes for this so can't wait to try them out. I'll post back with my results. I'll be running 87, since that's what's in my tank for now.

Thank Justin for the quick and awesome service.

 

Well just got to take the truck for a quick spin, about 6 miles. The thing I first notice was the throttle response, very impressed, no lag any slight touch and I can fill the truck wanted to move excellent there. Can't wait until I can really open her up.

 

have fun with it, i love my tunes from Justin!

 

Update, I had to do some data logging for Justin to really get my truck tuned the way I wanted it, and all I can say is WOW. This is how I expect a tune to be. I'm running 93 perf tune, and by far it's the best tune that I've ever had, and I had tunes from several different tuners. Justin at VMP, in my opinion is the best.

 

+1 on Justin and the quick service!

 

I'm very happy with VMP also, I love my custome tune and it is only 87 oct, can't wait to try 91 oct.

 

very satisfied with justin's service. he got my custom tunes to me quickly

 

Well, had a problem with his tunes throwing a p0172 CEL. I'm still waiting for him to fix it. It's been about a week now and haven't heard anything from him.
