Is that a good thing?

It seemed to be a pretty good thing until I pulled it back to idle with the mixture full rich. I was at 8,500' and it really didn't seem to like it at all...cough, sputter, cough. It did settle down and idle eventually while I was picking my favorite field...
I'm thinkin' that I won't do the idle thing again while full rich and fairly good altitude.

Intercooler added (with entirely new induction system), -K fuel system replaced the -F, Max rpm increased from 2575 to 2750 (should be 2800 but the A&P-IA "just didn't wanna go that high," and pressurized mags...that's most of the changes.
Already had the Merlyn installed earlier this year.
Net result seems to be that CHT is at least 50 degrees cooler and there is about 10% more power available from the engine. The engine controls feel very different since the fuel pump and throttle body have been changed and the governor was shifted two splines on it's drive shaft.
Obviously I'm learning to drive a "new to me" engine.

Final Approach
Ah! The first flight. I was wondering what this thread was!

Yup, first flight after repowering the aircraft. I think it is now pretty much what should have been envisioned for the turboDakota when it was new. If the intercooler has really solved the heating problem with the TSIO-360-FB then I've got a really nice mountain Cherokee.
Don't get me wrong, the engine temperature has been a manageable challenge. But it will be nice to maintain a climb without constantly worrying about CHT.
As an aside, the CHT never got past the half-way point today, even in slow flight. Prior to the intercooler slow flight was a serious challenge because the CHT shot up so quickly. Okay, it's November and the OAT was about 8 C so that helps a bunch. We'll have to wait until next summer to give it a real test.
