I am putting a 1900 Magnuson blower on a customers 2012 1500 Chevy pickup with a 6.2L engine that has VVT but no AFM.
We are also putting a Comp Cams small VVT cam with 214/228 duration and .559/.571 lift on 116 LSA. Also putting in there phase limiter kit and some better springs.
Keeping stock exhaust and converter so I don’t want to get carried away with the cam.
Has anyone ever messed with the VVT tables on one of these or will they work ok stock?? If I understand correct the retard at part throttle is simply for fuel mileage and figured it was probably close???? Maybe you should limit the tune to match the 22 degrees travel of the phase limiter???
However they are retarding the cam 3 degrees at 4000, 6 degrees at 5200 and 8 degrees above 6000 in the factory tune at WOT. Is that in crank degrees or camshaft degrees??? If its Cam degrees that seems like a lot. My guy at comp didn’t have any suggestions at all. Would you mess with this or leave it alone??? Probably won’t put it on a chassis dyno but might if I have to.
