5000RPM misfire with vortech VR7135

and for anyone wondering, the reason you get black soot on your tailpipes with LT headers is not a rich condition. It is because the primary cats are removed.

[jymbojym]

he means, will the WOT mapping adapt to things like headers.

Yeah that's what i mean... cause usually Full throttle fuel mapping is based on fuel pressure with maximum injector duty... and everytime we road test the truck we get better WOT response... i'm telling you man the i'm impressed everytime!

Alright now we dynoed the monster... 547WHP 507LBS/TQ... Nice LOL!

I just installed a complete Vortech kit on my 2007 dodge charger daytona. I'm having the same issues it seems as jymbojym was having. around 5000 rpm the car starts to stumble and misfire. i also have headers, high flow cats and a cat back exhaust. i called vortech and they said the car may run lean. i dindnt see anywere on the diablo that came with the vortech where i could add fuel.

Guess i SHOULD START WITH PLUGS FIRST?

Is it possible to add fuel with the tuner that came from vortech?

[mikel]

yes, in the modify tune menu you can add fuel to the vortech tune at WOT.

[oakleyp2]

in modify tune all i seen was:

ESP
Transmission
Tire Size

the Diablo Tuner I have came from Vortech.

can you please tell me the menu options to get to it?
