2015-2017 Mustang GT MAK Stage 2 Power Package

The Diablo i3 Tuner is top notch programmer, all the data logging anyone would need. I uploaded the 93 Octane Tune and Holy S*** the car WOKE UP. Completely makes a difference in where the car pulls harder from throughout the low RPM range. I haven't had a chance to install the Cat Delete kit yet, but from what I hear with other new mustangs who have them installed, I am not going to be disappointed. The quality of the welds on the pipes are very well done and very light weight. This entire kit is so much more affordable than buying a full header set up, I get the sound and performance + a tuner for under $700. Now I have more money to put towards other engine upgrades (still for less than a full header set up) Adrian from Mak Performance has been super helpful getting me set up with the tune for my car, so I give 5 stars for customer support and quality of product.
