So, I have made some changes on my own and when I get this thing tuned I hopfully will be in a good place mechanicaly as well. So, I went for a little drive with the changes made, and feel a difference. LTFT still short of course, no detonation and hopefully a little closer to my goal! Thanks for your help with the other matter, I will let you know how it ends up, Les.

Sounds good, once you start going wide open throttle you'll feel the boost coming in. Thanks Les. Bob

Sounds like a good plan, thanks for the order! Bob
