I agree, I don't know how Flaco is on his vvt, whether he cuts n pastes or go through it. But having the cheat sheet would really help I'm sure.

i'm just worried about the heavy valves. Read they give problems under higher mileage/hp trucks. Might be a nice piece of mind to change valves if reving close to 7K
Regardless they arent exactly "that" heavy its just a bad early batch of L92's ate valves and Im betting that it was crappy stock valve springs that broke causing these issues not the valves themselves. That plus first year anything is often the guinea pig so the L92 head/valves got off to a rocky rep but the reasons why are still up for grabs.
Anyways regarding EPS lobes they are not the most aggressive they are the most unique. Lobe design is more about timing of the speed of valve movement rather than the total movement itself. So EPS lobes were in fact designed to be easier on and off the seat allowing for more lift, without loss of valve control. Plus they were apparently designed around the PAC 1518 spring so... By the end of this summer I'll either be cursing the beehives, or raving about them cus Im gonna beat this thing like I always do LOL. Anyways regarding VVT thats a whole other dilema that Im too tired to bother with right now
But yes this board has always been a little on and off. I noticed when prices tp buy were more and more attractive posts went up and up too. Now it seems everyones waiting on the new truck comin
Shame really. The GMT900 is a sweet truck as a DD in my opinion and Id rather wait a bunch of years for the perfect new truck rather than be the first tool who buys one

TSP spent more time modifying those tables on the dyno that any tuner ever will.... The beauty of the supplied tables is that it takes that variable out of the tuning equation and makes it the same as tuning a non-VVT.
