Has anyone had a problem with there VPc/AFC setup hesitating at 2500-2700 rpms then smoothing out around 3000rpms. This is for a MKIV supra. Thanks in advance.

actually, i think mine does the same thing....i havent driven it in a month or so so i cant remember for sure, but somewhere around that area when you rev it too there the rpms jump around
Learned this from Walser and Javeman...there is a lean spot right in the RPM range that you mentioned. It is most noticable when it gets cold. I resolve it by adding fuel about 7% at 2500 rpm. That fixed the problem.
