Not currently. The dealer can flash for higher idle.
You can also use this JWT mod. It has worked really well for alot of the cars here.

No, I have the 287 engine.

We also have a couple of customers with a rough idle just generally that have basic mods and this cures the issue instantly.

The dealership should flash it for relativly cheap.. probably same price as JWT mod.. once UTEC gets idle adjustment the JWT fix would be useless splicing imo. Why not get the dealership to flash it using consult?

Won't this send the pressurized air when under boost out of the intake manifold and out the intake tube, basically a vacuum leak?

Good idea.

That's my car he's talking about and yes it idles perfectly now. Before, it idled like an old american muscle(I'm assuming that because I've never ridden in an old modified muscle car) but now it's like stock. No need to raise the idle.

I think that I am having this issue with the unsteady idle due to cams. But, the line that you tap into from the back of the throtle body, I already have tapped into for a fuel regulator. Has any one done this and had any problems?
thanks

So I did the install of the JWT kit, and the car is still running like but. I let the car warm up and then took it out and it stalled 3 times in the 1st 5 min. The idle is still very rough, though it has gotten a little better as I have driven the car. After it stalled the 3 times it do not stall after that. But, my fuel pressure is stuck between 2.8 and 2.9, is this normal? How long does it take for the ECU to learn the new AIR/FUEL? And is my fuel pressure suck due to the increase in vacuum?
