Have you had TM removed via tuning? What does your A/F mix look like?

Hmmmmm, very interesting. I have had similar KR issues, but my A/F ratio is way lean, around 13.5:1.

I have also had a tune, with TM removed.

how are you determining it is pulling timing 3-6 degrees ?

are you using a timing light or relying on feedback from the computer ?

dyno shows on every run @ about 2800rpm on up to 6500 HP drops as much as 20HP since it stays on low octane table car runs 12.85 best to a 13.5worst my tuner is stumped he has never seen it before
