I have always had a hickup in my tune whenever I hit about 3400-3600 rpm. It has always been there and never gone away and is consistant. Can't figure it out. Only thing I noticed is that my Link ignitor is not physically grounded, but the ground wire attatched to it is grounded. I have a Lem V4 with a wire in patch so I did not cut my stock harness. Not sure if it is wiring or the ecu itself.
Please advise
Thanks,
Ron
