[QUOTE="nate-roth, post: 16316429, member: 136703"] I run a Maggie TVS2300 with a CFM CAI at 9# and 24deg of timing on E85 through ID1000's. Car makes 660 and has been rock steady reliable but I did initially run into [URL='https://www.hotrod.com/articles/build-1000hp-fuel-system-2011-2014-mustang/']Build a 1,000HP Fuel System for Your 2011-2014 Mustang! - Hot Rod Network[/URL]high RPM fuel lean out with the stock pump and JMS BAP. Of course on pump gas I never had fueling issues, but with E85 I could not reel in my ST fuel trims above 6500. Instead installing a new fuel system I installed a 2015+ fuel pump with an adapter fitting, the 2015+ pumps have a larger outlet 3/8" as compared to 5/16" on the 11-14' pumps. The fuel outlet is the restriction on the 11-14 pumps. After the 2015 I have plenty of fuel, on my initial data logging after putting in the 2015 pump I had to pull about 10% fuel above 6500, shows I was trying to overcompensate the maf trims on the 11-14 pump to bring in the ST AFR. The idea for the 2015 pump came from this article [/QUOTE]
