decided to try the 411 swap into my 54 chev hot rod with a 1996 5.7 LT1. This swap eliminates the dreaded optispark unit. The optispark is now only used as a distributer and the crank sensor is used by the 411 to time the spark. 411 is out of a 2001 Express van 2500 5.7 Vortec. Started Ok with the stock tune with the vats shut off. Can't seem to rev the engine above an idle with the trans set to manual. I have a t56 in the 54. Runs fairly well when set for an auto tranny. Any tunes out there for a auto to manual 411 swap?
Thanks
