Just tuned with SEPST (SERT) and 117 kit (injectors, TB, 259E cams, etc) and SE Cam plate with high volume oil pump. Cobra 2-2 exhaust and 58mm backplate added to the stock Ventilator Elite air cleaner. I expected more from this build. Maybe lost too much due to 2-2 vs. 2-1 exhaust? Comments welcome.
Any thoughts about improving the Torque curve between 2500 and 3500 rpm? AFR Chart is attached as PDF.
I'm running an EV51 cam, Wiseco 10.5:1 forged pistons, Ported and polished heads w/big cam work, Bub's Bad Dog pipes, and a Thunderslide in the rejetted Harley carb, with a Hypercharger, in my 1997 Softail Custom FXSTC. I must add, I have to run Sunoco 103 octane with a little Lucas octane booster thrown in.

103hp! Not bad for a 21 year old motorcycle (with classic plates)! That's true. I'm too old to lie.

Spent 2,5 hours on the Dyno today to get these results after many runs. Pretty good numbers for stage 1, awesome torque.
Without the cats the Rineharts are really too loud, of the unbearable level imho, with 20 Nm less torque.
The 'before EFI tuning' numbers were the results after tuning with the Screaming Eagles without the cats in the headers.
Bike feels like Superman's bike now and the sound is OK loud and super deep.
