We all know that about 12 days ago HP Tuners released the ability to tune the new 2019 ZR1. The DAY that was announced we started the hunt for a R&D car. We flew to Ohio and bought a LMR blue one from Rick Conti (great guy BTW) Check out his VLOG, he invited Steven to his be a guest on his VLOG while he was there picking up the car.

Anyhow enough of the fluff. We got the car home this past Sunday and Monday morning we had already ordered the unlocked ECU from HP tuners and immediately went to work on the car. Our objective for this car is to build it in stages to show the ZR1 aftermarket what each little step offers in the build process.

Our car is a 2019 ZR1 3ZR with track package and 8 speed auto.

Step 1 was to baseline the car.
Step 2 was to tune the car
Step 3 was to put American racing 2 inch headers on the car.
Step 4 (not done yet, but probably pulley change)
Step 5 .....
Step 6 .....


Have a look at the results below. There is no funny dyno business here. What you see here is what you get. We were SHOCKED the car picked up 40 wheel from just a tune, and we feel there is more in it in that regard also. The car sounds SOOO good with the headers.

Green line is the baseline. Blue line is just a tune. Red line is with AR 2 inch headers. We're hoping with a pulley change we can touch the 800 wheel mark. That would be INCREDIBLE for just a couple simple bolt ons and a tune.

Give us a call at the shop if you have any questions! We have parts in stock for anyone that wants to do a similar build!








VLOG with Rick Conti when we went to get the car this past weekend. Thanks again Rick!

I didn't think things could be better than an Admiral Blue ZR1, until you started overclocking it. WOW, NICE WORK!!!!

New update! She made 800 rwhp with headers, tune, and lower pulley. Simple bolt ons without opening the motor, or without adding meth, or without touching the fuel system.
