I have the same problem with APR's chip, i'm waiting to send it back and get the upgrade, they told me it should solve the problem

See, I put the gist of the issue in the title.

It is very common to get knock sensor-based hesitation with a chip. Far more often than people realize. Try driving with the windoows down and punch it in second gear (along a wall helps). Listen for knocking. I was unable to hear very bad knocking with the windows down, and could only percieve hesitation. Gas octane varies widely.

This new version has now been released. It was held back for a short period so it could be implemented with EMCS. That way the trick mods made would be secure from preying eyes. It is a very smooth revision. We also will begin shipping the downpipe systems next week. This kit is a 345 hp kit. These come with high flow cats and straight pipe sections (for off road use only). They really open things up nicely. Feel free to give us a ring anytime.

Thanks

I called APR when it happened and they thought that it was the TBB, but when I checked it was fine.(That was a waste of an hour) So I disconnected the battery and did a throttle adaptation. That got rid of the hesitation, and all of the APR power was back. That lasted about a month, and I had to do it again on the weekend. It feels pretty good now, but not quite 100%.

I am going to call APR again about the problem.

Upgrade is free. New features (multiple programs, throttle adaptation/code reset) are normal price.
