and btw, mustang dynos are the MOST conservative dynos in the world. it makes no sense that any dyno would read lower than a mustang dyno, they are known for putting out the lowest numbers. what dyno are you using?
For all years except 04, you can remove 2 fuses and it will max out at 5K with full power. For the 04 the resoldering method may be the only way. The traction fuse for the 04 disables the spoiler, speedometer, and throws all sorts of codes. Eventhough it allows it to rv to 6200 rpm uninterrupted I'm pretty sure it is some sort of "limp mode."
Due to the odd nature of dynoing these cars, the highest numbers we've seen, and the only ones we compare against for product development, are from the Mustang dyno.
We are hoping to get on the Mustang dyno next week. The only one near here is very busy though, so I'll keep my fingers crossed.
