I just noticed this today... The IPR voltage at idle will fluctuate from .8-1.0. And when driving it'll fluctuate ( just an idea ) 1.8-2.1. About 2-3 tenths of a volt.

My HPOP has only 58k on it and I'm running 190/75 injectors. Just had the heads done at the same time I have the internal stuff updated ( stand pipes, stc etc )

Any idea on what's what? The truck doesn't feel anywhere near as snappy as it did prior to the studs/190s. And by snappy I don't mean spool up, just horsepower and torque wise.


edited: I did change tunes and the TSD SPD did go up to around 4.1v and I'm on the Daily Street now and it only gets to 2.9-3.0v at WOT.
