I have a 09 FLHT, 96 inch, SE Heavy Breather, SE 58mm Throttle body, 5.3g injectors, Stock head pipe, and Vance and Hines Muffs. Anyhow, I'm having trouble tuning with the SEPST. I originally had V&H True Dual head pipes also, but the bike was darn near impossible to cruise with. Ran like a stripped *** ape as long as I kept the wick twisted WFO. Went back to the stock head pipe, cruises a little bit better, but still falls flat @ 80 mph and 3000 rpm. I'm pretty sure reversion is killing me, and was wondering if anyone's had any luck tuning the reversion out. I just put S&S 585's in my 11 RG CVO, played with the ve tables a little, and it runs great. The 11 has a D&D FatCat pipe, and I'm wondering if I need one for my 09.

 

Thats going to be a tough one to tune. Injectors are to big and too much cam for a stock 96".

 

It's going to get a S&S 106 kit this winter. I guess I should of "splained" it better. I put the 58 mm TB on because my stock 50 mm was giving me problems, i.e., throttle plate hanging up. I was thinking of putting the stock injectors back in until I get the 106 done, but was hoping they would be "tunable" for a 96". Cam selection was also based on going to 106 in the near future. My 110 RG loves it's 585. It had the stock 255 before the change, there is no comparison.

 

How about a bump now that everyone's back from Sturgis

 

Stock 96 compression is way too low for 570s. Not gonna have any low end no matter how/who tuned.
