So we ordered some Comp Cams for my buddies 2010 GT500 and we get everything installed. Trailer the car to the dyno and get it ready for some tuning. Then we find the car will not stay running from the transition from vacuum to boost. We dick around with this thinking it is a tune problem for a week. Get all kinds of people involved in sending their own base tunes to see if they could get it to run.
So 1 week of getting nothing accomplished. We decide to bring the car back home and start looking other places. First we pull cam covers off and re-check the cam timing. Everything is ok there so not helping us. Then go and check all the sensors to be sure nothing is wrong there. Nothing....
Then I make a call to Justin Starkley from VMP Tuning about our problem to see if he wanted a shot at sending us a tune. Well after a brief discussion about what the car had done and what was going on, he starts to ask the questions...So I go dig up some of the answers as he had very specific questions about Part Numbers....
Well long story short he ran into a problem years ago during a magazine article for MM&FF about installing Comp Cams and Springs into his GT500. The Intake Spring that they recommended was grossly under rated on closing pressure and causing the intake valve to be pushed open with minimal boost. Apparently he has made Comp aware of this and they have done nothing.
I just got off the phone with them and the Tech already knew about this problem and told me the replacement parts I needed to order. So instead of selling the correct parts the first time they sell them to you the second time and make you have to pay them more money and wait for the wrong parts to be returned. So now I have $450 tied up after spending $2500 on cam crap the first time and have to wait to return parts to get my money back.
And here is the TECH!!!!! If you order cams for you GT500 here is the correct Valve Springs and Titanium Retainers for the car.
Intake Spring - 26125-16
Exhaust Spring - 16123-32 (You only will need 16 but they only sell by 32)
Intake Titanium Retainer - 791-16
Exhaust Titanium Retainer - 798-16
