remaping question?
I might be taking my 2008 superglide custom to the dealer tommorow to get re-mapped now that I have went to a full exhaust system compared the the slip-ons it was tuned with.
The dealer said I may be able to get away with doing a quickie tune of about 2 hours because the bike has already been mapped for the air cleaner and all I changed was the pipes.
Should i be worried that im not getting a good, full map or could this be a legitimate situatiuon?
Thanks

Personally, find a better tuner. You didn't really need to do anything to run change either the ac or exhaust, but not both. Individually they might make a 1%-3% differance in performance. The two together make a 10%-15% improvement in power. By what logic the dyno tune for that 1%-3% ought to be fine for the 10%-15% is beyond my imagination and I have a fairly creative imagination.

I missed the slipons. I thought he was running just the stock exhaust with the ac. I will certainly defer to your expertise. I'm hobbiest without a dyno, you're a professional with one. Assuming he had been running the stock exhaust would you disagree with what I said? That being that just changing the ac would be a small change, but the ac and exhaust together is a big change.

Actually, just the opposite. Harley doesn't consider pipe changes a stage I. In other words, you can add slip ons with out re-mapping the ECM as long as you have the stock A/C on the bike. The stock A/C is restrictive and really "chokes" the engine down. The stock mufflers already breathe more than the stock A/C will allow, so if you change ONLY pipes you'd be o.k. But in this case he has an open element A/C, it is choked down by his exhaust, when his bike was tuned to his original set up, it was tuned to the more restrictive exhaust, since he has a freer flowing exhaust on it now, he has more air flowing through so he would be running lean in this situation, the tune will richen it up allowing more fuel.
The download is a "safe" alternative to the tuner. Harley keeps it pretty safe to protect the bike (and their warranty). If you run the download you won't have problems but you won't be getting optimum performance from your bike. Not to mention that it's a 1 time deal, if you want to make any changes in the future, i.e. cams, you'll be getting the tuner then anyways.
