Confused Newbie!

Well, looks like you have a real nice set of upgrades for reliability and economy. I would say your next step for power, economy, and reliabilty(PHP seems to be regarded as one of the safer tuners, for gas and diesel), is a FICM reprogramming and ECM/TCM rollback(hover mouse over blue letters/words for a description). This would be partially dependant on what your current strategies are now, but it is likely that you might have a less desirable one if you recently had mileage drop after the visit to the dealership. I'd say here are you two likely options:

1: FICM reprogramming and ECM/TCM rollback, then purchase a Gryphon and use that for power programming and monitoring.

2: FICM reprogramming and modified ECM/TCM rollback. The modified ECM/TCM rollback can be your power programming, but you will be unable to change at your leisure. Gauges wouldn't be a bad idea for this being you wouldn't have a Gryphon to do your monitoring.

ECM engine control module- engine management, just as it sounds
TCM transmission control module- transmission management
FICM fuel injection control module - I'm going off of memory, but in one conversation I had with Bill, I believe he described it figureatively as a 'fuse.' You can have all the programmer you want, but if your FICM isn't programmed for it, the FICM won't allow the extra juice.

Hope this helps!

Oh... and welcome to the PHP Forum!
