Default looks bad, feels the same

Different dynos do different things, attached is my dyno run at Performance Cycle on Sat. the 4th. Divide the torque in half, it was a faulty setting, but the airfuel was what i was after, he says its good, but a bit on the lean side , i suppose i could play w/ the PC3R, but i wouldnt know what i was actually doing. Great seeing you Joe, and great seeing you Jen, i never got to check out the under tail jen, but Joes bike is sharp.

I found through trail and error that the best map for at least my bike is the one for a completely stock bike. I was never able to make more power or get any less flat spots with any other pre fab map from PC. I really do not believe that dynojet sat there with every bike, with every exhaust /intake combo and R&D'd a custom map for it. The PC3 would then cost about $10,000 if that was the case lol. Also if you compare most similar maps, ie, stock bike to ones with some kind of slip on, theyre not very different. Something else you could do is call your exhaust manufacturer to see if they have a map they can email you, or perhaps they can reccomend which one from dynojet comes closest for them.

They do make those maps for every exhaust they test. The way they do it is people come in with X bike with Y exhaust on it that they have never tested and make a map for it. It's not that much work with a PC3 to do that. But Every bike and EVERY pipe is different so the only way YOU can have a map for YOUR bike is to have one made! Sounds too simple but its true.

as far as re-mapping a bike because of a slip on isn't needed. If you've gone with a full exhaust and replaced/modified/removed any emissions equipment then you should remap. If you've done more than that such as modded your intake, changed cr, changed fuel psi, head work, cams, etc then you have to re-map. These are pretty basic rules to follow.

Another thing you have to remember is that the maps from dynojet are strictly a starting point. As mentioned every engine is different even in the same year, same model. Also note that alot of dynojet tunners only tune for good a/f ratio's. This doesn't give you the best performance. This is also why someone who has the same bike as you but has tunned their bike based on real world results will walk away from you if you've only tunned based on a dynojet run.

I mention dynojet directly because most dynojet owners/tunners only adjust maps based on a/f. Other types of dyno analyse differently and therefore the bike is tunned differently.

I could probably go on for pages but this is good enough to get people to look for more info and gain a better understanding of things dyno related.

There was one case where someone put a Devil slip-on onto a '04 Gix 6. No other mods were performed and right after the install the bike's idle was very uneven constantly jumping from 600 to 1,000 rpms. So would that call for a re-mapping?

even stock bikes should be dyno tuned and possibly remapped. the fluctuation in the idle might have always been there, just more noticeable due to the extra db's being produced now.

remapping will even help a stock bike, let alone one with just a slip on. as far as the "pre-fab" ones that you could download off thier site, they are submitted by dealers and tuning centers that have made and tested them, and not usually by dynojet themselves. keep i mind that different conditions will make bikes have different tuning requirements, so what was made and works best on a rainy November day in Seattle may not be so good down in New Mexico.
