Who's paying $800 for a COBB?? I got mine for $650 months ago & there are more floating around now since more people are trading in their N54 335's |

And I'm in the Springs. Having forced induction is a must - I had several NA E90 and E46s - I'm a firm believer in boost at altitude now. . And I remember our sig/avatar when the fires were going - it was pretty crazy, but was nice to see support from around the world -Rich |

Sorry if this thread got confusing for you from the amount of propaganda from inexperienced users going on in this thread.

Yes map 5 should auto-adjust to 17.5 psi, but it depends on many things such as IAT's, outside temps (I've noticed fuel trims max out easier when it's colder), ignition timing curve, and the type of JB4 board you have.

No, but I did talk to Terry over the weekend and although his solution works as designed, it's not able to maintain the volume demand that's required. I'm sure eventually Terry will find a solution, but I can tell you the FFTEC / Vishnu solution does the job. I'm still running my stock LPFP and didn't get any LPFP codes and my car was running 100% E85 over the weekend and putting down 422 rwhp and 448 ft/lbs on a Mustang Dyno. All in all that's good news for everyone who wants to run e85. Can't wait to see what upgraded turbos will put down, because RB's have a lot of room to grow with upgraded fueling and e85.

My flex sensor showed 79% Ethanol. Prior to the pump install I would code after shifting to 4th at WOT. So after install I was launching in 3rd at the event and pulling through 3rd, 4th, and 5th trapping between 150 to 160 depending on traction and cross wind. So regardless of what tune you run, the pump will allow you to run 100% as long as you address the fuel trim issues with the DME.

Do you have any gas stations that sell E100 though? E85 contains up to 85% ethanol, which obviously varies.

You're right, I should have clarified, What I mean by 100% is my gas tank is 100% full of e85, with the sensor reading around 83% ethanol, I have yet to come across a station with e100

I know Terry was talking like it could be a limit of the HPFP now, but I don't agree. I think FFTEC has the answer, but time will tell. I personally don't know all the details, but my car did very well running 100% e85 and my stock pump couldn't hang before.

Isn't Terry running 520+whp on E60? That is a lot more fuel than 420whp with stockers and 80% Ethanol. The low pressure was holding for him, it was the high pressure that was dipping. I don't understand how more low pressure could fix the issue if its already holding and high pressure is falling? Am I misunderstanding?
