So glad I seen this video. I was about to do a VVT Delet on my LT5 engine. This made me definitely change my mind. Why are so many people on you tub doing a VVT Delet? Is there any benefit in doing a VVT Delet?
So I did it I installed a VVT engine in my 2004 GMC non vvt truck after driving it for a while the only thing I noticed is I need to dial down the injectors pulse other than that lots of power the computer doesn't know it's supposed to be connected Had to buy lots of adapters but it works didn't want to cut up the wiring harness can be seen on my RU-vid channel
On GM gen 4 and gen 5 with stock cams, I usually tune out the retard below 3000, but keep the upper rpm retard stock. This gives strong down low power and throttle response by removing the EGR effect but keeps HP climbing. Just have to remember to change the VC spark table afterwards. It seems on LS stuff the retard down low is mostly for emissions reasons.
My car is tuned already making 90hp more than stock. I did not touch vvt adjustment at all. How do I know what will gain power and is it safe to advance to Max or just like with spark timing there can be knock?
When advancing cam timing you might get into knock as well since you are increasing VE on the same RPM, I'd say if you want to give it a try use good quality knock phones to catch it and pay attention to your AFRs.
