I know this question has been asked before but I was wondering if my solution would also correct the problem. I have a 94 GT with the AODE tranny. Put 4.10 ring and pinion in the rear and correct speedo gear but my shift points are still off. I hit the rev limiter before the transmission shifts. I read a post on here that said to get the speedo recalibration unit from summit for around 100 bucks. Unfortunately I read that just about 5 hrs after purchasing a MSDBTM unit from ebay. My theory was that if I installed the MSD I could just change the supplied rev limiter chips to the 6000 rpm range allowing an extra 500rpms for my tranny to shift. Will that work or do I need to get the speedo recalibrator thing. If the MSD unit will not correct the problem anyone want to buy it? My future mods are a DSS 331 stroker and turbo hence why I went with the boost retard.
Any insight would be greatly appreciated.

Well bieng that our rev limiter is set at 7000 putting a 6000 pill in the msd aint gona do a thing. BTW why did you get the MSDBTM are you running boost?

he obviously plans to run boost.

Yes the boost retard is for the future, not running boost now. My car hits rev at 55-5600 rpms not 7000. It shifts about 100 rpms after the rev so 6000 would work. Will the MSD unit override the stock rev limiter though?
