I have been playing around a bit with my 06 3.9 G6 GTP to get a feel for HPT so I am more confident when I go to tune my TT GTO.
Anyway, I have a couple questions-
1- I was trying to lean it out a touch while cruising for slightly better MPG- should I just change the stoich to a leaner # and let it run from there, or is there something else I should/could change? I have added a couple degrees to it in cruise and such and it seems to be a bit better, but I was wondering if anything else can be played with since we have no "lean cruise" here .
2- The car seems to "buck" on a hard WOT shift. I always thought it was TM closing the throttle on an abrupt shift, but I set all the values to max and it still does it. Is there anything else that would do this? It almost feels like it is slamming the throttle shut for a brief second on a hard shift. Not that am going to race this thing, I have the GTO for that, but I do want it running it's best .
