So take out a small loan and invest it into a performance built transmission, a higher stall TC, and a dyno tune! Say.... 3500 stall?

Here'* something interesting I saw in 92-99:

What are the chances that sluggish acceleration could be due to a vacuum leak, particularly a leaking MAP? What about a faulty MAP?

Compare your MAP to others.

One thing I notice about my TPS adjustment on th SSEi is that it'* far too sensitive in unlocking the TCC under light throttle. I don't like it.

Another thing to think about is that the PCM is still dynamic. It can learn your behavior, so what'* the point of the TPS mod? Particularly if you have a performance PCM?

Good points, Bill. I'm thinking I'll have Doug snag the TPS off my spare throttle body and bring it to me this weekend. I'll install it and see if anything happens.

I brought up the MAP thing because in the course of removing it many times over the last couple of years it seems to be losing some of its orange rubber seal. Not sure if it is problematic, but it'* worth looking into. I'll check my MAP values this weekend and report back.

Is your MAP sensor just an o-ring? If so, get before and after values from it. At idle and specific RPM'*.

Try to duplicate conditioons for the before/after as well. Same temp and humidity, at the same coolant temps, etc.

It'd be nice to have others with L36'* then provide matching data to compare to.

No it doesn't, neither does DHP, both for good reason. Taking out all Torque Management on an otherwise stock, and perhaps well used, tranny is good prescription for a trip to the tranny repair shop.

big_news_1 it'* time to invest in a good scanner.

Sorry I can't compare MAP values as I do not have a map sensor.
I would definitely get that map sensor o-ring replaced as well as stoping the egr from letting in un metered air. The egr opening is just as bad as a vac leak when it opens.
I doubt the gasket between then UIM & LIM is leaking unless you cracked it. Those gaskets are tough.
