however i'll raise my AE enrichment tables from the 25-35% by another 5% and see how it goes.

Yes, this is similar to the problem I had if I remember correctly.

But, another issue that I see, is that the PCM has different tables that it uses when cruise control is on. This includes TCC lock/unlock, shift points, etc. So when using cruise, my car will drive different, and get knock going up hills because of these different tables. So if I see a big hill coming, I knock the cruise off, and control it myself so I don't get knock. Just one of those things where more tables would help us tune our cars better. But, I don't see us getting access to those things.

But kinda offtopic, I would like to have my TC engage a little firmer. Is that possible with HPT?
