    I'll throw in my 2 cents worth ... LS1B would take care of most of my vehicles I tune.

    LS1B as well. Seems to be an issue for anyone with an 80E and an aftermarket torque converter.

    Bump...would REALLY like to see this. If it can only be for 1 PCM/TCM, Id say T42 first then T43 (dont know if these do it or not, havent tuned enough of them) then LS1B.
