ECM and torque converter programming
Put an 2004 Yukon gen III LM7 5.3l/4l60e into my 36' Chevy coupe. The factory computer has had an initial tune by Frost that is geared towards HP, motor has not been fired as of yet but real close. The only remaining drive train mod is the torque converter. I have a 2300-2500 Monster converter ready to install but would like to test drive the build, prior to this modification, with the factory converter. The ECM has already been programmed for all the mods including the new Monster TC. Is there going to be a problem test driving this build with the factory Vortec converter (stock is roughly 1650 rpm) prior to the Monster TC upgrade? I'm guessing the shift points will be off, anything else? The only modifications to the drive train are a small street cam that has a .600 lift, 216/220 duration with a lobe separation of 112 degrees, LS3 90mm throttle body (DBW), Holley Sniper 90mm sheet metal intake, headers, dual exhaust and an 8.8 Ford posi that has a 3:70 gear with 265 70r/15 rear tires. My goal is to fire the engine, do a small amount of test drive time, swap in the new TC and get it too a tuner for final tuning. If all goes well should I limit my drive time on the factory Torque Converter so I don't hurt the trainy?

Perfect and thank you for reply
for over 4 decades but this is my first LS based motor and my first conversion motor using a computer driven system, I have no idea what to expect. Thanks again!
