first off, thank you for all the great info. i was able to convert my 5.7 mercruiser to tbi this spring. it runs pretty well, definitely better than the quadrajet that came off. I pulled the ecu/harness/sensors out of a truck with a manual transmission. i do not have a vss or o2. i have not attempted to tune at all. I was just wondering if anyone has a tune available for the 7747 that eliminates the o2 and vss and optimizes for high rpm (3500+).

the symptoms i would like to get rid of are:

1. slight bog when rapidly going from idle to WOT.
2. seems to run out of top end about 4,000 under a load.

thanks!
