1. I had the chip set for Jody's 40hp tow tune. When going up hill...the ICP would ramp up to about 2900 psi...and the truck would just fall on its face. Shake...shimmy...EGT's climbing. My hpop gauge would hold steady at 3200 psi. If the truck downshifted...it seemed to come out of it. I put the truck in stock...and never had another issue. The ICP would jump to 2800 psi...and if the truck downshifted...it jumped to 3000-3100 psi. No shake, shimmy or anything. Does this sound like my little AB injectors are having issues...like blowing the checkvalves open...or at least floating them?
Did you replace the IPR when you put the Stealth
pump on? A wobbly ICP reading MIGHT be an indicator of an IPR that's on it's way out (but hasn't failed completely)
2. Noticed a shutter when turning under power. Feels like something in the back end... Any ideas?
What the other guy said--try some friction modifier in the rear pumpkin if you didn't use any at the last service.
Is it time to go back to the 195* OEM thermostat.
That's what I'm going to do. I never noticed any performance/mileage improvement with the 203 t-stat and since I'm coming due to swap one out anyway at my next major service interval (kept using it through my switch to Fleetrite ELC), I'm going back to the 195* stocker.
