1988 454 Tow Vehicle ECU Chip Recomendation

I have been thru that before and it needs to go on a chassis dyno to be done right. I would convert to a carb if it is legal in your state. If no you need to keep your advertised duration below 260. I have installed many Comp 260 cams with performer intakes with good results. I would put in a performance timing chain and gear set and advance the can 2 degrees. Than advance the timing 2 to 4 degrees. These mods were for the TBI engines. Also headers will help.
