I will be replacing my 4.8 with a 5.3. Will the 4.8 program run the 5.3 until I can get it dyno tuned?

<div class='quotetop'>QUOTE(-HIC- @ Apr 17 2006, 07:16 AM) [snapback]50294[/snapback]</div>It will start and run, but I would not put in under any serious load (no aggressive acceleration, no towing, etc.,) until you got your tune. You could also get your pcm done through mail order and put off the dyno time till you have all your mod parts installed and ready to optimize.I will be replacing my 4.8 with a 5.3.
