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

I'd say to see if it's an issue with the higher demand for fuel. If present with stock tune then I'd consider it something that's on its way out. With this type of issue I'd be logging as much as possible to watch it. I'm not qualified to dig through those data points like the gurus around here, but I sure do like reading what they find. Very informative for us learning.

Yeah i didnt think the tuner(torrie) did anything wrong it would be the same with any company. I should have known something was wrong when he had to dial back the base tune, i just wasent sure what was going on and liked the way my car felt. I think I will run the fuel cleaner through it few timea and then send him a log of the last tune he sent me to see if there is a difference. The car feels much smoother with the tune so i will probably just drive with it but not really beat on it much. I dont even know where else to go with this and will just wait for something to happen. Its too cold and I am too busy to run a stock datalog at this time.SHOnUup said:
Could be. I am waiting for fomoco to let me know if my car can upgrade to 13+ fuel pump and might just do that. I have a feeling that would fix an issue since this pump cant keep the pressure up. Only explenation in my mind is the pump or its cloghed up which the cleaner should hopefully help.SHOnUup said:

Give some of the Lubegard fuel system cleaners a try.

This has been proven to clean and safe on DI vehicles. BG them self used this on there SHO

Yup... Start at "Results are in"... Yes BG is Good and helps., no doubt.. No doubt, but only mechanical cleaning has helped the coking of intake valves or the turbo blades (CC blowby... Especially the front turbo).... Just the difference in turbo'd GDI engines....all manufacturers, in fact Ford's system is relatively good compared to others like BMW or VW.Josephm said:
I agree... And it is a good service... And cleans injectors and cylinders well. Plus improves performance....
This was the end of the article in a well done test actually on our cars... The parts I refer to are below where they say:
"Even at the first check-up (5,000 miles), borescope footage showed intake valve deposits forming. At each subsequent check-up, we noticed deposit buildup continued in the intake valves and intake ports. There was heavy deposit contribution from PCV gases."
"...our borescope videos showed BG 44K® cleaned up piston top and injector deposits."
"The results are in
Near the end of the test, at about the 55,000-mile point, our pros started noticing more performance issues.
The conclusion from the two-year test was that BG 44K® can help keep performance high (combustion chambers clean, injectors clean), until deposit formation on the ports/intake valves built up enough to affect airflow.
“Until design improvements address the negative contribution made by crankcase vapors (which create intake deposits), Direct Injection (DI) engines will continue to have intake deposit buildup issues. DI simply lacks the necessary and traditional fuel rinsing afforded by indirect injector spray. The high heat environment experienced by the fuel injector tip is also a major contributor to driveability issues,” says Dustin."
Solutions that specifically address reducing PCV vapors (engine oil evaporation) would be a welcome advancement by the manufacturers of DI engines. A combination of full synthetic, low volatility engine oil, combined with reasonable drain intervals would be one way to decrease these intake deposits. Dustin continues, “If DI is here to stay, then classical methods of engine ‘keep clean’ will need to be re-vamped to ensure trouble-free engine durability and performance.”

Hey, Z! I have suspected fuel quality being a problem in my Edge for some time, so I took your advice and added HEET yesterday to the gas tank (after fillupZSHO said:
) at the Shell station where I get crappy gas (87/93, doesn't matter). Today, the Edge felt strong driving/acceleration was good, almost normal! STFT also did not need as much enrichment, and timing "retard" became less needed further along in the drive. Hopefully improvements will continue.Great to hear the good news,honestly been using the yellow bottle for a long time know,when i used to work on my BMW's always through a bottle or two all season long,some people think its only for winter lol, cheapest and most effective bottle you can buy,ordered a case of 24,maybe i'll send you a few.ZSHOdded said:Hey, Z!
