Default Update on Fatcats and tune...

Hmmm..very disapointed in this initial set-up. I had stock headpipes and Bub7 slipons - 83/98...great AFR and rideability was great.

Now I'm at 80/94 stumbles, bad throttle response but good AFR...rideability factor down tremendously. Backfires, stumbles at acceleration, and pops on deaccelleration.

Lot of dough to have these results. I left the bike with the dealer and said..."fix it".

Stay tuned...for updates...

Any way you can get a copy of your dyno sheet with the A/F on it posted here? Can you get the MAP of whats on it now from the tuner?

I left the dyno sheet in the bag for the GM to look over. I'll have lunch with him Monday and grab it and scan it in. The AFR's on both the Bub7 set-up and the Fatcat set-up are good...the Fatcat one is a little more waving where the Bub7 was more straight across.

I did that the dyno has a part missing that's on order...I'm hoping that's my issue...

I agree the tune is wrong or at least poorly done.

I thought I'd have gained a minimum of 2-4 hp and 2-4 ft lbs better on the TQ. You can imagine my surprise when I saw 3 hp and 4 ft lbs tq less...

Anyone else running a similar set-up..?? 103 Stg II/Fatcat..??

Your Propipe is driving some of those good numbers. I had those in the past, but they're not made for my '09. I wish they were. That is the best pipe for my kinda of driving and the performance I seek.

Found the problem....bad, very bad base map the tech started out with. That crap map stopped any chance for the pipes value to be seen.

Since then, the dealer put a different tech on it..great idea, and then began with a different base map. So far, so good...HP and TQ are back up to above where I started.

Stay tuned...the tune will be done today..I'll update...

The tuner should've know it was a crap base MAP while he was tuning it. Plus he sholdn't of shipped it like that. Hopefully they figure out how to tune, to bad they have to learn on your ride.

Stuff like that really pisses me off, Techs not taking their time, while dealer charges you up the ---. Why put a junior tech on the dyno, without your best guy mentoring. I see why guys go in and request a certain guy. They get the job done right the first time. GOOD LUCK, I hear good things about that fatcat.
