Yea, I had too. Powerdyne is 3 weeks late shipping the damn Blower. I
know, I know, but I don't have an extra PCM laying around, actually I do but
it's in pieces being worked on;-).

Wait a sec....you installed the PCM before the Blower?

Shawn, it's designed to work with the blower (retarded timing and
enriched fuel). Wait until you get the blower installed...them see what
happens.

Hey folks,
        Just curious, I'm waiting on a PowerDyne supercharger and had my
PCM flashed by Leach for the SC. Well, now at WOT I flat line at
4900RPM, no stutter, not like the engine is dying, almost like a
governor plate on it. It stays PEGGED on 4900RPM's until I let off, what
gives, WTF? When I back off the throttle it will shift and then flat
line at 4900 again. I'm wondering whether I'm just out of air and
dumping fuel that can't burn or if Leach set my RPM limiter WAY too low
and messed the shift points up. Below are my current mods, then the
rest of them I'm waiting on. I could really use some input on this one
as it's REALLY annoying:).

Thanks,

Shawn
