AC issue after H/C
Finally got the H/C done and up graded to a 2002 computer and had a speed density tune done.
But now here's the problem my AC compressor cycles on and off at idle, we checked the freon level and it's fine in fact we pulled it down and did a full recharge.
We even raised the idle speed to 750 rpm but it still does it.
Anyone else had anything like this?

Im NOT a tuner but,,,,,,,,,,,,,,,,,I do know that there are tables in the PCM that need to be adjusted to allow the PCM and HVAC system to operate properly together after a cam/head install. 
ENGLANDGREEN adjusted my PCM to compensate for this VERY ISSUE and solved it!! Thanks EG!

Corvettebob1 - that is a tune issue and an easy fix. Get your Tuner to fix it - it is NOT a mechanical problem.
