Oh, the horror...
thanks for your reply......yes, i do understand the VE tables...that's ho i tuned my space ship Harley, by the VE tables.....it's close, but i never put it on a dyno.
my mechanic does have a dyne.....i as there the other day going over all the **** i need done on my frontend......but i know he'll do a real good job on the tuning, just don't know hat he'll charge and n reality if i just save a few more dollars i'll get a WAY better product than if i go with the Hyprchip deal.....not tha that's a bad option......buy once, cry once for real.......
i couldn't believe the difference in tune i needed JUST from a cam change in my pretty modified Dyna........imagine the XR750 Harley motor....she was suckig in 115% on the volumetric efficiency.....no that's sure maximizing. intake and exhaust are CRITICAL for a real proper running machine.
