Evening,
This weekend I installed the vette servo and it made a hell of a difference. I've been tuning on 93 octane, have all TM removed, and the mods listed in my sig. Before I installed the vette servo I would sometimes get a few degrees KR from 1-2 shifts at WOT at the track but never more than 3 degrees. Well I did a WOT pull yesterday AFTER installing the vette servo and got 8 degrees KR!!! I'm thinking that maybe I should put some TM back in for the upper rpms so that it pulls timing for the duration of the shift.

Has anybody else experienced this? And what would all of you gurus suggest for this issue? Thanks a ton!

 

You should be able to tune for knock sensor sensitivity, when you shift, it may be hard enough or something is hitting the frame somewhere to throw your knock sensors off? Just a thought

 

yea it could be that. I just thought other people might've had this issue before, but I guess not. Hopefully I'm ok. think im goin to the track tonight, try to break into the 14's.
