Hey guys,

Man I beat my head on this one but I ended up getting it, after nearly redesigning the fuel sytem. With the stock tune from Diablo/Vortech he was going deadly lean at 4500 rpm's. After a weekend of work to the car and some major tuning revisions I finally got it straight.

444rwhp and 387 rwtq

This was a totally stock 05' manual with the Vortech kit and the Aftercooler. It had alot left in the tune but I stopped it because the stock fuel pump was still being used(focus pump) and the stock spark plugs. I know we could have cleared 480 and possibly 500 but I didn't wanna scatter the 3500 mile motor.

I wont go into detail about what I had to do but I'll say this, Vortech's idea of fuel system upgrades is completely wrong. I removed the Walbro Piggy bank pump and ran the stock pump and made more fuel pressure with it.

I forgot to get the runs from Blake but I emailed him so I'll have them soon.

Later Doug.
