Spent the morning down in Long Island at Performance Motorsport in St. James, NY, which was the closest authorized Uprev tuner. A big thanks to Adam and the guys there, who were very knowledgeable and great to work with. (..: THE EXPERIENCE - TEAM PERFORMANCE MOTORSPORT :..) Alot of nice Z's and G's there, which is always nice to see .

With that said, my stock map never got Dyno'd, so keep that in mind when reading the graph below. It accidentally got wiped when [i don't know what happened] and what you see below is an untuned map and then the tuned one. They claimed this dyno to be somewhat of a heartbreaker, but we all know numbers should be taken somewhat lightly.



Max WHP = 320
Max WTQ = 244

As you can see, the AFR is much more linear.

As for the butt-dyno, you feel the car pull significantly more from the 3k-6k range, especially in 3rd or 4th gear. Overall I'm very happy with the outcome, and look forward to a little more driving!

I think it's in my sig, but I have Stillen Gen 2 intakes, Stillen Headers, Stillen HFC's, and Stillen Dual Exhaust.

Thanks for the review! 320whp on a Mustang Dyno is great!

But I have to point out, a baseline is very crucial in pre and post tune.. I'd ask for my money back if they failed to give you one

So, you basically don't know the actual numbers you gained from the tune? Just basing it off the butt dyno?

Unfortunately, that is correct. I think we have seen enough others on the Mustang Dyno though to know approximately what the numbers would be before the tune.

Thanks, yeah it is noticeable! 3rd and 4th gears especially have new life for sure.

It made me happy to hear from the Adam in the shop that a NA 370Z they had recently tuned made 315whp with very comparable parts, (replace the HFC's with straight pipes, but I don't think it had headers). Along those lines, he said for us G37/370Z owners on a budget, you should see the best bang for your buck with test pipes and a tune.
