Hey guys, Ive got a 2004 Roush 440A. I had the car dyno tuned back in April and everything was good at the time. Now the car is starting to act funny on dyno tune and it runs normal (Besides being rich due to long tubes) on stock tune. I think I may have a fuel pump going out (These cars run a twin pump setup) at idle im sitting at 52-54% FPDC and im hitting 100% FPDC at 5k rpms. It also has a weird hesitation every now and then running WOT, going to shift gears and getting back to WOT it falls on its face before picking back up.

The fuel filter was replaced 6 months ago. I had been having a crazy idle issue the past few days that turned out to be a bad TPS.

I ran a data log on the car, do any of you have any way of viewing the data log and seeing if you see anything out of whack besides crazy high FPDC? Any help is much appreciated!
