1994 ram 1500 5.2 too much cam for stock ECM
 
Hello mopar friends. I started out with a 1994 ram 5.2 so a few weeks ago I blew a driver head gasket. The truck has 200,000+ miles. So I decided to pull the motor an fresh in it up. I get te heads to the machine shop. They magna fluxes both heads. It had a crack between both valves on #1,7 an #2,8. So I bought new heads. Supposed to be beefy in the spots that had cracked. So I decided to go ahead an rebuild. So I had it bored .040 over an new everything. Bought a BIG cam .512 intake an .520 exhaust. With 208 & 214 duration. Roller cam. Everything new except block, intake, ECM, and crankshaft. So now my stock computer is bogging down my motor. What do I need to do to fix the problem. I'm $3000 in so far. Please help

You need to have someone tune the ecm to match your current setup. Most people will write tunes for a few hundred dollars! good luck!

Definitely need that aftermarket ECM re-tune. A side note, that stock intake runs outta steam around 4,000rpm, cam peaks near 6k.

Kind of a big cam to put in a small displacement engine in a big truck.

Agreed. Without a gear swap and a high stall converter that things gonna be a pig off the line no matter what programming you get. And with the stock intake it'll suffocate at higher revs.
