    Shift point WAY OFF after shift kit+converter

    The Car:
    95 LT1 Z28, 4L60e
    I've adjusted my shift points multiple times and it has always worked very well. The actual shift comes ~200RPM later than what I program, but that delay is expected and consistent: setting to 5800 brings a shift right around 6000, setting to 6300 brings a shift right around 6500, etc etc.

    The New Parts:
    I just installed the following in the tranny:


    • 2400 stalled torque converter
    • Servo from a Corvette
    • Shift Kit (RatioTek)


    The Problem:
    The car now shifts at 7k rpm.


    • Was there something I was supposed to change in the ECU after installing a shift kit to keep it shifting properly?
    • Is there such thing as a shift kit which not only hardens shifts, but actually delays the shift point them as well?
