Well one of the best pieces of advice I've heard on these bike forums is, "buy the tuner that your tuner guy uses". A bit of background story first :
When I bought my bike last year, I went with the Fullsac package with the TTS tuner. At the time, I figure I would do it myself, and would never need a custom dyno tune.
No complaints with the TTS and Steve at Fullsacs map- bike ran great and dyno'd well, up until recently.
The only changes I've made this season is new plugs and wires (SE 10 mm wires and HD platinum plugs), and Rinehart 4" slip ons. Also ran some Seafoam through it just for good measure. About a week ago, I noticed my bike pinging slightly for the first time. Only happens at WOT (in any gear), and just does it just for a couple seconds. I don't think it was the gas- I had one tank full (87 octane) when I first noticed it but didn't think the noise I heard was pinging, so I refilled different brand gas (87 octane), meanwhile it was still doing it, then my shop guy took it for a boot and advised that it is engine ping that I'm hearing.
Since then, I put in some Lucas ocatane boost, and I don't know if it helped because I avoided WOT since then since it's harmful to the engine, but all this made me come to the conclusion that I really should get a custom dyno tune done.
So here's the problem- nobody around here tunes with the TTS Mastertune. Well, I shouldn't say nobody- there is one shop, but he doesn't have a dyno and doesn't come recommended anyhow. There is a guy around here that is supposed to be the best tuner around (and specializes in doing engine work and tuning on 110's), and he only tunes with the SEPST. So, as much as it sucks, I ordered a SEPST from Jenni, and will take my bike hopefully on Friday to get a custom map done by him, which will get rid of the pinging, and give me piece of mind that the bike is running at it's optimal best. That part doesn't suck, but what does is that from what I understand, my $450 TTS is now a paperweight, since it's already married to my bike, unless hopefully someone can tell me otherwise
