Drag Strip tips and advice needed.

Ok, I just got back from the golf course. I checked the TPS on the EFI. I could only open it 57% with the pedal at the floor. Doh. What an idiot!!! I previously got the rpms up to 5800 or so and wondered why it did not have more. I guess there is more. I adjusted the throttle cable (there was slack) and cut a bit of the carpet out. Now at least I am at 87%. I will try where it is tonight, datalog all the races and post tomorrow.

. What tach do you recommend? I have never looked at them.
I believe you found the missing HP.
