Disappointed. Do u suppose the lean appearing A/F area is reversion or overlap with the 4.5 hitmans? My powervision shows no knock events and it is still making HP and Torque.

 

or injectors maxxing out. Not for nothing, something is missing there. My 95 inch with mild cams and mild headwork makes more power at less compression

No, it is lean because it isn't tuned correctly. You actually lost 14lbs of tq as he kept tuning. Run 1 was 114, run 5 is 90????

 

Find someone who knows how to run a dyno.

 

Here is a better graph. I discovered latter that he did not have the O2 sample tube far enough up the pipe and it is reading reversion at the crossover in the pipe...(S&S 2-1-2 header).

 

If the injectors are maxxed out wouldn't it read lean at the top end?

 

What year bike? White band injector? I doubt it is an injector issue.

You have white bands, and they are enough to support this build. I have done several FM B level head tunes with several cams. Your numbers are low. I would conservatively guess 105hp and115 tq.


Sample tube is a red flag. Being an ATV shop is another. There is better equipment out there and people that specialize in HD's. I'd suggest you cut your loses and find a Harley tuner.


James is a straight shooter. I'm sure others will have suggestions as well. Best of luck to ya.
