socom22 Posted October 18, 2008 Report Share Posted October 18, 2008 I'm wondering if anyone knows if I need to have my PCM retuned after I install the 2800 stall converter? I already have a tune from Wait4me, and Jesse had adjusted the line pressure and removed some of the TM. If anyone has a positve answer it would be greatly appreciated. Reason being, I'd put my stock PCM back in while the trucks in the shop and not drive it until the retune came back from Jesse. Alittle economy of motion. Thanks in advance...

js_silveradoSS Posted October 19, 2008 Report Share Posted October 19, 2008 No. It is not nessary. I would have the TCC (Lock-up) Converted to non-PWM. Bascily on and off. Quote Link to comment Share on other sites More sharing options...
12'SROCK Posted October 19, 2008 Report Share Posted October 19, 2008 yes you do need a retune, your mph/shift will need to modified as well as TCC lock up Quote Link to comment Share on other sites More sharing options...
