Default I Want PCM

What do you modded 97-99 SSEi'* have for PCMs? Somebody has to have something for my LSS. I thought the governor was a 3rd gear thing only. I now I find out the darn thing works in overdrive too. Crazy thing.

Yup, it'* an Oldsmobile. The Buick Riviera SC'ed, and Park Avenue Ultra are the same -at least the series II L67 are governed at 108/109. My mom'* 1993 Park Avenue Ultra on the other hand, doesn't stop there.

You might call Intense and see if they can do a custom PCM for you and if not, look into one of those Jet in-line PCM'* that Merlin just inquired about. Not sure if the Jet removes the speed limiter though, but if you are serious you could put a zener diode in the speed-o wire to the PCM -just have X2 what your speedo is showing as you don't want to get caught running along @ 130 mph when your speedo says 65.

I just found out the Regal GS is governed the same too. Does that mean a PCM for a GS will work on my car as well?

Slightly off topic but anybody know what my car tops out at? Last time I tried I think I hit 103mph but that was over a year ago when I first got the car and since then Ive had my tranny rebuilt, put in a used engine, and whatever else is in my sig. If its governed Im guessing maybe 115? I havent really had the opportunity to try it but then again I never want to see a ticket again in my lifetime.

I still say check because if that were true then he could just use a GTP DHP and he can't.

I've checked every source out there and 2.93 is my gearing just like the SSEi, GTP, GS, and Ultra. Why is it I cannot get a PCM anyways?
