Base run max: 67.47hp, 82,11 torque
Best dyno run: 72.19hp, 84,64 torque
For comparison, my 04 Road King (injection) with 95 cid, 203 cams, SE high-flow air filter and SE 2-1 exhaust produced 80.06hp and 90.12 torque after being tuned by American Eagle H-D in Corinth, Tx.
With the map the dealership provided I noticed no hesitation in the throttle response, it was only after the dyno tune that this started to occur, on cold starts particularly (felt like a carbureted motor that hadn't been warmed up properly). I am interested in real world performance and drivability first and foremost so when I had the motor nearly stall on me several times, that could easily have resulted in a dropped bike. So I had the dealer (which is not H-D of Greenville) put the first map back in. Now everything is back to where it was and there's no hesitation at all.
Planning to have a 103 build done on the bike in the next couple of months which is really why I'm inquiring about good tuners in my area.

I would love to see the graph of the tune MM.....my email is
hdmd88@yahoo.com.
First off let me say the numbers you got on the '08 are right in the ball park for the mods you have. I believe it is unfair to expect the numbers you got from the RK with a set of 203 cams installed compared to the stock cams of the '08. I consistently get 84 hp and 95 tq with a small Andrews 26 cam in the 96'' motors and I'm sure you would be there also with your build had you installed a 203 or 26 cam.
The hesitation from the FlyByWire throttle body is something I see alot of following modifications and tuning....it's not a good thing and I agree with you it is dangerous to say the least. Harley has known about this issue for a while now and one of the things, that where sent out in a bulletin, to remedy this was to cycle the ign switch 3 times with a 5~6 second pause between cycles....this worked when I did it but it had to be repeated when the bike was off for a length of time. As a tuner I truly believe we should have control over the sensors and servo motor on the TB when we use the SERT but we don't, hopefully that will be an option in the near future. I have found that playing with the VE tables in the 3%tp ~4%tp along with the idle position at 5%tp I was able to eliminate 90% of this lag time we are seeing in the FBW with Mods.
Every time I do a tune with a SERT there is a new situation that pops up that I learn from and I've been tuning and teaching the SERT for quite a while now so it is a on going process to say the least. I said that to say this, I know Eddie is a good SERT tuner, does he know it all.....of course not, did he let the bike go out the door with a problem.....it looks as if he did, but this doesn't make him a bad tuner. I will bring this to his attention so it won't happen again and I truly believe you should bring it to his attention also.... people learn from their mistakes and he will learn from this one which I grant you he will grow from.
I agree with you that the lag problem was in your tune other wise it wouldn't have gone away with the other down load you had installed, but again that problem has proven to be in the 3%~5% throttle position not through out the complete tune.
Thanks for the information MM and I will address this with Eddie, hopefully you guys will talk and reach some kind of compensation for your grief and inconvenience.
Thanks
Doc
