I can turn a distributor to set timing and re-curve one to change the max advance, vacuum advance, rate of advance, change jets to get more or less fuel... and all that makes sense butt circuit logic, .HPT files, VCM suites... I am so lost.

I have put plenty of SRT cams in other 5.7s with no tuning and no issue, only more HP and other 392s in 5.7 rigs but never run across this issue, I am betting something is sticking in the phaser.




I was on the phone earlier with Ric, he says there is a spring loaded lock pin in the phaser , that keeps it from going the full retard at low RPMs, he was wonder if some how it got stuck, dis the truck feel sluggish over 2500 before it threw the code and went in to limp mode ?



It's taking me a while to get my head around the tuning aspect of these Modern engines.
