    I never knew 87-93 had 190 hp. I always thought they all had 210 hp except for the 95 which had 200 hp and 310 TQ.

    What did GM do to the 94+ TBIs to gain 20 hp?

    I know the 96 has 250 but the 94-95 has 210. What did they do to go from 190 to 210 hp on the TBIs?

    All I know is that they got better tuning for the 94+ I wonder if they got 20 hp from just that.

    94+ got better programming. my 93 dynoed at 145 HP a couple years back so 190 flywheel sounds right.
