Time & light rain weather limited my testing to 1st & 2nd gear. I would give it a 25% increase in power to the the new 8600 rpm redline. There is a definite increase in power. 25% increase for approx $400 including freight is a really good deal. I've spent $1900 to go from 170 rwhp to 190 rwhp on my 1st hayabusa. Over $10K + on my turbo hayabusa. Brisk would be my definition of upgraded ECM acceleration. Everything else other than new 8600 rpm redline & improved acceleration appear to have remained the same. More info to follow with time & weather permitting.
