Default Lost in power when VAC = 0 ??

Hi Guys,

Actually this is nothing new for me, I had been driving around with this result for couple of months.

At normal driving condition, monitoring boost gauge its easy for me not to get into boost while daily driving to save on gas.

Only at partial thottle, when the boost gauges reads 0 Vaccumm, where just in between that point before boost. The car seems like its not moving at all, lost in power atleast.

Is this normal?



Thanks guys!

If the red LED on your Autotune is coming on at that point, your O2 clamp may be causing your ECU to add too much fuel. If this is the case, turn the screw on the pressure switch clockwise to raise the pressure at which it kicks in the Autotune.

Ah.. sorry OG, I totally forgot about telling you guys that.

I had set the AUTOTUNE pressure switch to come on after 0.1bar ( 1-2 psi).

@ 0 Vac, the RED LED was never on.
