Looking for ECU/CHIP for 1992 5.0

[Nathan26]

I recently did some upgrades to a 1992 GT 5.0 and the stock ECU isn't happy. The larger cam, heads and injectors have the AFR way out of whack. The car runs but is flat until you hit 3000 RPMS. Here is the list of upgrades:

TrickFlow R- Series Intake
MSD Ignition
Aluminum Heads, 185cc intake, 70cc Exhaust, 64cc combustion chamber, 2.02 intake valves, 1.60 exhaust valves
.499/.510 lift cam, duration 285/292, lobe separation 112 deg
24# ford injectors
roller rockers
larger throttle body
cold air intake
headers
smog delete

We basically did everything we could without stroking the engine. I didn't want to upgrade to a 9" rear end or swap the transmission and drive shaft. The car had 37k original miles on it and is MINT. I had the same car, year, color and trim in high school and regretted selling it. This was a "pre mid-life crisis" project! I'm looking for an ECU or chip that can be plugged into the ECU to maximize the upgrades and allow the car to run smoothly. Any suggestions or feedback would be greatly appreciated!

If the MAF is not calibrated for the 24 lb/hr injectors that could be your problem.

I'm running the BBK 76mm and the MAF is for 24 lb injectors. I just ordered the AMP Mega Squirt from LMR with the Serial Adapter.
