You also don't moniter FP, do you? IF you don't, you have no idea if your fuel pressure is dropping to dangerous levels at WOT, cruising, or even idle.
My truck, at 60,000 miles, was running 50ish at idle and pulling into the high 30's at WOT with a hot tune. Too low for my tastes, I installed the fuel reg. upgrade and have been sittingt at 65 (idle / cruising) and 60 (WOT) ever since (90,000 now). Cheap insurance for your injectors, if you ask me
