Dyno Tune needed?
So, I have a friend (Really. It's not me. I already have my Stage 1 done, and am very happy with it) who has a 2010 Electra Glide Limited. It's 100% stock, but he's doing a Stage 1 soon.
The guy that's doing the work is cutting out the cat, drilling the plugs out of his stock mufflers, and putting a high flow air cleaner on it. He's also installing a tuner, I don't know what brand, I'll ask.
Fine so far, right? (although I don't care for the sound of drilled out stock mufflers. I did it to a FXDX once, and didn't like it).
His "guy" is supposedly taking his bike and putting it on a dyno to tune it. I suggested a canned map was probably going to be all he needs, and he'd see very little increase in HP or TQ by massaging the canned map on a dyno. He disagrees, and is paying for dyno time. Fine, I tell him, prove me wrong and show me the baseline run on the canned map, and the improvement once the dyno tune is done. Now, he says his guy won't have a baseline to compare it to, as that's a waste of expensive dyno time. I called BS, he got pissed and told me it's his bike and he trusts the guy...
1) Am I wrong, or don't you have to have a baseline run to see what and where you plan on tweaking the canned map? Don't dyno runs show before and after HP/TQ numbers? If nothing else, just to show how much and what that expensive dyno time accomplished?
2) How much (if any) increase in HP/TQ are you typically going to see by "dyno tuning" a canned map on a simple Stage 1? As there are literally 1000's of bikes out there with the exact same Stage 1 pipes and air cleaner, how is one motor going to be significantly different than the other 999 of them? If anyone actually has a Stage 1 dyno sheet comparing a canned map to a dyno tuned map, I would really love to see it.
Also, I'm not afraid to be wrong. I just want some proof, as I can't make logical sense of what he is telling me. If it really makes a difference, then hell, I'll pay to have my bike put on a dyno, and get my canned map tweaked too...
I hate that motorcycle they make me ride. I'm here to tell you there ain't nothing in the world I hate worse than that elephant under my ass.
