You have the SE tuner and the tech likes it and feels comfortable with it, so in your position I would stay with the SE.

 

It's not artificial intelligence in chess match. There is nothing wrong with piggy back systems in general except potential packaging challenges.


Agreed. Just get a dyno tune.

 

I had the SE Race Tuner installed on my 2003 FLHRI at 40,000 miles along with S&S 510 gear driven cams and the upgraded HD oil pump at HD Fullerton in CA. The bike was a stock 88ci except for SE stage 1 air filter and Vance Hines oval slip on mufflers. Fullerton tuned my bike on their dyno and I was amazed with the power gains. All my bros ride 96 or bigger motors and now I can slowly walk away from the 96ers. Still can't beat the 103s but I'm very happy with the Race Tuner, cams and dyno. The SE Race Tuner has never failed or given me a problem. I now have 82,000 hard miles on the bike. I have had to replace the fuel lines in the tank a few times due to pin holes (should be a recall) but the SE tuner works perfect. The motor even runs cooler now and I can run regular gas without knocks until it gets above 110 degrees air temp (I live in the desert. One of my friends got the same 03 RK but put a Power Commnder on it with a dyno tune and Bub True Duals. He has had many tuning problems and his bike has always been slower than my bike. Another thing to consider: There are few shops that know how work on a PC system, but nearly every HD shop knows the SE Race Tuner and many independents also know it. Peace of mind is priceless.

 

Thanks very much for your input $tonecold and Sparks, I believe I will stay with the SE tuner, your feedback was exactly what I was looking for guys.

 

power commander does not trick the ecm,it is downstream from the ecm,it changes the signal to the fuel injectors.guess u could say it tricks the injectors,but they just use the signal they get what ever it is and wherever it comes from.
