87 Buick Grand National 3.8t on MS3PRO Ultimate

Postby williambavila » Sat Mar 18, 2017 2:49 pm

I have successfully managed to wire in the ultimate box in my Grand National. I had rad factory wiring and stock style chips up to this point and am looking to get this car a little faster with the new system. I have been told by many it wont work and others tell me I am a fool for trying to reinvent the wheel. But it is in and made my first few passes at 20#s of boost with no issues. I just wanted to share this with you in case someone needed some help in the future. I have had some help and am thankful for those that have helped.

Nice! To hell with the nay sayers!
