    95 2 door tahoe 7427 PCM

    Hello everyone, I just got a 1995 2 door Chev Tahoe with the 7427 PCM. I have heard nothing but good on the 7427. It is my understanding there is only 1 VE table with this PCM. I grasp tuning idle, BLMs, etc..now how would a guy go about tuning the VE with 1 VE table? thanks!

    The 16197427 has two VE Tables and two Spark Tables, Near Idle and Off Idle.
