I don't know about the sound symposer, mine seems to still be running? I did put a new exhaust in last week, so maybe I just haven't noticed it shut off the symposer because the exhaust is louder than stock.Well, I just ordered a ProCal tune on the cheap for a couple reasons.
1. I wanted to upgrade the intake for better throttle response / sound, the FP paper conical filter fits the bill (was gonna order one back when Juben did the group buy on early production units but never got around to it) which is half the cost of the kit, paid $450 for the whole shebang on a lucky score.
2. I need the ford programmer to change the darn axel ratio since doing the GT diff swap, speed is correct, but I have a feeling the odometer isn't, while I have low enough miles it doesn't make much of a difference, it may over time. Local dealer said they don't have one and literally told me to go buy the FP programmer which costs $250 by itself anway or go to a shop...
3. I've been debating OAR with other members (I could be wrong or I may be right, we'll see), I've NEVER once seen a value of -1.00, but am on a quest to see if any tune can achieve a -1.00, be it stock, FP or LMS. That would answer the question about fuel quality and how my car is running.
4. It will be interesting to see how the FP tune feels comparatively to stock and LMS 91 on a tank of 93.
5. I can fully disable that darn sound symposer with the FP programmer. Hooray!
Thankfully all my current mods are stock compatible, which is why I avoided the DP as much as I wanted to try one, I wanted to maintain OE PCM software comparability in case I ran into issues, in case I needed stock to pass e-check or if I ever sell the car and I'm glad I did! Time will tell after the holiday what the logs show, got some long trips coming up so should be a good opportunity to get some big logs in some cold weather. The only oddity is the 160F thermostat, since the fan profile is set for 180F stock unit, however I ran the 160F thermostat with stock tune, it just lets the temp creep up to 20F higher, but once you let into it, cools back down, so small swings in temp isn't a big deal.
I think the Ford tune shuts off OAR? There's a setting in the calibration that has OAR ON-OFF and by default it's OFF. I chatted with an FP rep online about it and he said to leave it off unless there's a problem.
