I will say that when I LS swapped my car, the LT1 MAF I was using for my 96+ OBD ECU carried right over to the 99-02 LS1 harness/ECU no problems.
Same MAF I believe was used 94-97 right?
That's one less thing possibly, although what the tune is looking for in regards to MAF reading vs RPM/Throttle is a different story...
