I have no other mods don't know if that makes a difference but it has not helped at all. Feel like stock had more to it. Mid and high RPM is very noticeable with an overall smoother feel in general. That's prob my favorite thing about the tuner. I haven't messed with much of the other options other than the MDS being turned off. The roll on power is fantastic. Very noticeable compared to stock. Shifting is weird. Noticeable whether your getting on it or not. Sometimes scary how hard it shifts and some of the sounds that come from under your feet. I'm not worried about anything falling out just not as smooth as stock. Haven't figured out gas mileage cause I'm to busy going fast. Gonna give it some more time but wanted to put some more info out there on top of all the others that are out there. Love the gauge features btw.
I just changed from the 87 tune to the 91 and had the same low end power loss you just described. My 87 tune was fantastic for power and response throughout the spectrum. I thought the 91 tune might be a little better. I'm going to stay with the 91 for a couple of more tanks. If nothing changes, I'll go back to the 87.(gas is cheaper at 87 anyway!)
