I wish I could find someone with the tuning tips. I read this on Gear6's site where he said it was stupid to run a vacuum pump. He's the only person that I am aware of that said HE could tune up MORE VACUUM.
Other than uping the idle, what tuning can you do to the Roush. If I put a 500 cfm Holly on it the vacuum would go up due to the higher volicity through a smaller hole. I think this is called Burnuli's principal.....Something like that anyway. With the 750 or 770 have you heard anyone state how they achieve more vacuum from a tune? ANYONE?
Vegasmike? You've talked to him, how does he do it? tom

by changing the timing - with a british car - the mgb 1800cc 4pot - the timing was set by adjusting for max vacuum at 800rpm then retard until the vacuum dropped 1/4" from memory - last did it 20+ years ago
found this when I when searching - google is your friend
