I just datalogged my truck and i was wanting to see if i could get some input on what i need to get my truck running to it's full potential regarding eprom changes. I have several mods: scat crank/rods, flat top pistons, dart 180 heads ported/polished, performance plus crosswind intake, headers/true dual no cats, 50mm tbi, tbi spacer, airaid cai, msd distributor, 190 fuel pump, afpr, 2200 stall, msd al6, mail order prom, comp cams xfi280 roller cam (full roller setup lifters/rockers) no egr. 1995 chevy 350 5.7l. no gear swap yet. Need to know what changes need to be made to prom still new and want to start on my own. Mail order chip can only get me so much. thanks.

 

The one thing that jumps out at me is the camshaft specs, that is a HUGE cam for what you are trying to do. The head ports are too small to take advantage of the cam and the torque converter too tight for the cam. Stock gearing and the weight of the truck are not helping either.

 

understandable. I will be regearing, but thats about all the major changes i will be making for a long time. switching heads will be a no go. overall is there anyway you can checkout the data and let me know what changes i need to make. or some direction as to what i need to be looking at. Thanks.

 

Lets assume you studied the stickies. Have you done a datalog and viewed the result? How does the vehicle run on the mail order chip?
