Any suggestions on whether or not it will be needed with the Enforcer stage II? I know it is recommended, considering the S/C doubles HP on the stock transmission. Any help is appreciated

I have found that when you alter the valve body in any way, it not only affects upshifts, but downshifts and on these transmissions, what benefits upshifts makes downshifts worse. I'd leave the valve body alone.

However, the stock TC stall speed is around 2700 rpm. Lowering that will help. Rebuilding the TC would be my choice as well as installing a aux cooler inline with the one in the radiator.

Cool! Sounds like a plan. Thanks for the tip

Planet 10 used to do performance rework for Hyundai automatics... you might try to look them up.
