Re: New Mod!
A note if anyone else follows my method here.
I wish I had run across this before I purchased my second PSC-1. Fortunately I picked my PSC1-003 up new in the box on a dodge forum for $85.00 shipped.
The PSC1-003SF has a step size of 6.3mV and a range of adjustment of +/-0.625V.
I have the PSC-003 with +/- 2.5V adjustment and in 25 mv increments. Our MAF sensors are so sensitive if you are running stock MAF and have no plans of changing MAF sensors I found that the adjustment is fairly course. -0.250 or -250 milivolts moved my wide open throttle air/fuel ratio more than a full point leaner.
