Thanks guys. I've put a hose (3/4") right in front of the elbow in HHO injection area to keep the opening close to throttle body (about 2 inches away). I am noticing little improvement in acceleration. I am now going to dial the PWM down to keep output about 1LPM. My amps keep floating though, sometimes I am seeing 30Amps sometimes I its 20... any idea why does it happen (does it happen with you guys too)?
Thanks for the great help again!! I will draft all my findings and things I did to improve performance so it may be helpful to others also.
