I'm so new at this and there is so much I don't know. Here is what my dealer is telling me. If I install the monster ovals and the race tuner from Harley he needs to tune the bike. Could take up to 5 hours. He also said the download might be fine without doing anything else. The problem is the dealer is 4 hours from my house. He is the one that gave me the best deal. WHAT SHOULD I DO?
There are numerous members of this forum with more knowledge and expeieince than me, but here's my $0.02. This sounds like a decent dealer. What I believe he is telling you is that he will install your parts, download a map to the SERT, then put the bike on the dyno to check the results. If the download is a good match and the dyno numbers look reasonable, then your done. If the download is not a good match and he has to do some tuning with multiple dyno checks, then you are looking at a half day or more.
I would ask him if that is the plan. If the half day or more requires seat-of-the-pants tuning rather than a dyno, I'd check elsewhere. If possible, I'd also ask around to see how much experience this dealer has with dyno tuning and satisfied people are with the tuning results.
For the expense of the SERT and pipes, I'd install the larger air cleaner and opt for the tuning. This takes the guess work out of everything and you will be much better satisfied with the result.
Hope it works out well for you
