1994 Silverado Engin swap

[Herman]

Hi I am Herman and new to EFI tuning. I have just completed an engine swap in my 1994 Silverado, 5.7 liter to a 7.4 liter 454. My engine builder did a lot of work to the engine for me: Cam upgrade, heads have been reworked, Eldorbrook intake and headers. Up graded TBI with bigger injectors. Need a good tune for this project. The truck has a 16197427 ECM, also this is on the labor BJLH. I think it should use a $OD mask. Just purchased the APU1 Auto PROM from Craig Moates. Up loaded Tuner Pro RT ver. 5.00.9209.
My truck has an upgraded 4l60e from Hughes Performance.
Looking for all the help I can get to master a good tune.

Thanks in advance

There are several way to go about "Tuning" the 454 with $OD. One method that has been successful for me, was to copy / paste all the 454 parameters from a $OE chip into the $OD chip. The link to gearhead-efi $OE information: http://www.gearhead-efi.com/Fuel-Inj...Information-OE
