What could be the reason for my fuel system to be far more deficient then most?

Hmm good idea! If I do the 0-100 with the stock tune and plugs gapped for the tune could that possibly damage something? I returned it back to stock and on my way back to work the car drove fine but felt like it’s not as smooth as before. If I did get a log can you guys check it since I have no idea what I am looking at anyways? I can possibly get it done tomorrow.

I'd think the most appropriate thing to do is leave it be, for a condition which could presumably worsen. But whatever. Just throwing my thoughts out there. Most engine tuners want an optimally running engine. And hell, pre-EFI, it was necessity.SHOnUup said:
The car will run somewhat richer because the spark plug gap is smaller. It won't hurt anything, especially for the short period of time you will be running the stock tune; might see a slight mpg drop though. Better than running lean, which would cause detonation, which is a big no-no for a turbo'd engine.

Well I called to see how much exactly it will cost for the fuel pressure, volume and injector leak down test it would be so i can schedule an appt and now they quoted me $247.50... i guess the $100 is just a general look over. Thats bs. Lets see what the stock tune log tells, if it shows low fuel pressure then its worth getting it resolved since more then likely they will see the same thing and warranty will cover the repair.

Here is the process to reset drive cycle readiness.
Well i got an appointment for Monday to get the car looked at I am just worried it wont show anything since its stock again. I will update you guys and will try to get that stock datalog up this weekend. I actually will be dropping it off at the ford dealer this time since they will not charge me for check up. Also i was dumb enough to post a pic of my vin in here instead of just doing the pm and now am worried some ford rep saw it and marked my car as modified in their system.
Hopefully they will find the issue and then you won't be charged for diagnostics. It looks as if you pulled your vin down so if you still want me to look, let me know. I'm curious about backwards compatibility anyway for those folks who may run into issues out of warranty. If you're going to replace, might as well upgrade if there is an option.ElvenSho said:
Well I just picked my car up. They couldnt find anything wrong with my car and told me to bring if things get worse. According to them there was no fuel system issue and pressure was fine. I am noy sure what else I can do I guess I will tune it again and try some fuel cleaner in the system.

No dummy lights or error codes. Not a big surprise.
