hey guys, i was at the dyno again today, came up to these problems:
at ~8psi and 23* timing the car revs perfectly in 3rd gear(th400) all the way to 7200. as soon as boost goes up to ~22psi and 14* timing the car will NOT rev past ~6k rpm's.
im running 38k mile old coils (they have been sitting for about 2 yrs while the car wasnt running) HKS DLI, nkg bkr7e-11 plugs gapped at .020.
at 22psi and 14* timing im not showing knock voltage above ~1.5 volts, the engine still runs smooth, no backfiring or anything, it just wont rev past 6k.

any ideas?
bad coils?
