Fueling map issues?
'99 Speed triple.
I had the TOR high mount and the TOR high mount tune (9898). I wanted the stock exhaust since it's quieter and stock. I like stock. So I purchased it from a member here. I had a chance to install it today and I also installed the stock tune (9897). I started the bike and let it idle for about a minute. Started great, revved great in neutral, so went for a spin around the block. Right off the bat it was horrible below 3k rpms. It was surging pretty bad and felt like it had no power. After 3k, it ran beautifully.
I went back to the garage and installed the 9898 map. Bike started great, revved great in neutral, so I went for a spin around the block. It ran great, no issues, no hesitation, no surging, no loss of power.
Ok, I decided to try the low mount TOR tune (9899). The bike started GREAT. Quicker than it ever has before. Revved ok in neutral, a little hiccupy but not bad. So I hop on and go for a ride around the block. The fueling under 3k wasn't as good as the high mount but better than the stock map.
So that's where I'm at right now. Why would a TOR high mount map work the best on a stock exhaust? The bike was never very warm, so would the 9897 map or 9899 map be better once the bike is warmed up? I'm seriously at a loss. It blows my mind the 9898 map is running the best while riding. Do I have another issue I should look into?
