NEED 1228291 PROM!!
Need 1228291 prom please! No longer available through gm. This is the "updated" factory prom that fixes some driveability issues, false dtc's, and raises the torque converter lockup speed to 41 mph instead of 20 something. Thanks!!!

Re: NEED 1228291 PROM!!
Got one from my 86t/a ws6 305tpi I took out when I dropped in the vortec 350. Worked fine for me. Got to check the number though. Never had any
driveabilities problems and lock-up was good. Let you know tomorrow.
Also got one from hypertech called the thermomaster you might be interested in ? It's for the 305tpi.
