This is a re-post from my personal build thread, click here to check out the dyno sheet:
Mag Black Kielbasa
I spent a few hours at their shop and I have to say theyre definitely a very chill bunch and more importantly, they know their stuff. 2 other Z owners and myself were made to feel at home the entire time.
The owner tuned my car himself. While HP didnt show much change, my TQ numbers got a nice boost in the 3k - 6k range. They corrected my A/F ratio, which had been a bit lean from all of the bolt-on air modifications you will find in my sig. Removed the speed limiter, though its unlikely Ill be crackin 150mph any time soon anyway and slightly increased my rev limiter to about 7600.
I didnt expect a huge bump in the numbers, but it was definitely nice to see the TQ gains especially in the range that I hit during spirited driving. Most important for me was cleaning up the A/F so that my car believes and drives as if my bolt-ons came that way from the factory. The drive home felt really smooth, but I will update after I put a few more miles on it.
Overall a great experience and I will not hesitate to bring my car to these guys with any future modifications I sign up for. If you are in the Northeast and definitely for you Long Island guys, Performance Motorsport East is a great place to bring your rides.
