a crankcase full of fuel will set a low boost code also due to slow piston speeds!

Mine does too. 06.

Even with foolers in place. But level 5 on SMARTY at least and no problems.

Too much timing and too little torque management will set the code with a laggy turbo. It seems some of the 2006s have the most problem with this.

Bring the fuel in a little slower on the bottom. Does your turbo clear up at what boost? All the way till WOT?


OK, got a CEL on the first setting today. I will try the 3rd option next.

Thanx.

Get rid of the boost fooler. Those will cause low boost codes on the 06 trucks. Just let the Smarty do the boost fooling.
