With a quick phone call to Vast Performance, Prince was able to help me out on relieving the problem. I know you guys are on eastern time and weren't even technically open when I called (an hour after they were closed) but still was there when I needed help without even a second thought about it. That's what I love about you guys!!!! Unconditional support of everything and anything our cars! Big thumbs up for you!!!!

Can't wait to get my new set of main o2 sensors so that my CEL stops taunting me lol.

These guys will help you out, no matter what the problem is, as long as they can. I highly recommend them to EVERYONE!! But come on, we all know this already . Awesome awesome shop with "bend over backwards" support!! Cant say enough good things about them and to all you wondering....no I am not getting paid to say this LoL

KEEP UP THE AWESOME JOB!!!!!

P.S.
Prince, thanks for the extensive chat about everything regarding the stage 3+ setup on my tip and everything we need to do and prepare for. You will definitely here from me as soon as my car goes out of winter mode! I'm ready to bring the beast out of the car LoL.
