Jeees guys.... I know i need to get to the prom burning thing but. I can't shake the codes. When I use the Stock Prom I get a Code 33 and when I use the aftermarket prom I get code 32 and 36. I get detonation any way I go but it shifts better and has better response with the aftermarket prom...What's the deal? AND, when i start burning the prom should i use the stock or after market prom? The stock prom is for 327 rear end, the aftermarket is for my 273 rear end??????
