Buddies GSXR750 Quits at 80MPH

A friend of mine bought an 06 R6 with less than 400 miles on it. Once we got it home it would fall flat at 8k rpm in every gear. Only mod on it was a Yoshi 3/4 pipe(?).

We checked pretty much everything that we could and found out that only the first bank of injectors were working and nothing we tried worked.

He bought a Power Commander...had it dyno tuned and from that point on it ran like a scalded dog.

It made no sense to us or even the guy that tuned it why/how just the slip on pipe would affect this but all I can say is once we added the Power Commander it ran to redline with no issues at all.

Maybe there was an ECU issue and this corrected it but we had already tried the disconnect battery thing a few times with no luck.
