My mod are:
TOGs//Stge III ZZP Blower//LS1 tb// 85 maf//XP cam //105lb spings//3" Dp& high flowcat//3.2"//Ud plly//Msd wires//Aut 103's//CAI//DHP 1.0 Power tuned.

Reason i'm asking, is because i ran a 13.6@100mph 1.9' with 17* timing on the 3.2" with blips of kr at the track.
If i wanted to trap higher i would have to had added more timing,which= more KR.
My car has been a pain on the a.... to tune.
With 1.9's rr i traped 99.8mph can't remember the timing i was running.
Any input is appreciated!
Timing is everything my friend. I wish you have hptuners so i could take a look at some stuff that i'm pretty sure is causing you these problems. Every car is different yes, but that setup should not have to jump to a 3.4 to run 20* of timing. I'll bet there's some glitches in your tune that's killing you. I'm sure i can read a scan or two, why don't you post some up? There's plenty of darn good help on here to give you a pointer or two and maybe help work out your problems? FWIW I trap 106 non-i/c'd on 1.9 rockers, so... I would first change your plugs to 104's those 103 are way cold for that setup, another i have a feeling of a vac. leak, maybe check around for that?
