Message: [QUOTE="yzrmbsg, post: 580143, member: 8557"] What mine does....DP Tuner on any +hp tune....Truck hits 22-25lbs, CEL comes on with overboost code....it does NOT de-fuel. A couple minutes later and the light will go out...or I can clear it with the CTS. Using My CTS as gauges..... with the DP Tuner, the CTS will read above 25lbs, I believe the highest I've seen it read was 30, 31, somewhere around there, so to answer the OP's question, yes, the MAP sensor will read above 24lbs as long as the de-fuel is shut off. I was under the impression that the CEL cannot be turned off with the tunes, but only the de-fuel can, as when the MAP sees whatever magical number that trips the computer to de-fuel because of overboost, it sends a voltage to the CEL to come on. And the only way to prevent the light from coming on, is to install a (insert brand name here) regulator, so that the map sensor never sees above around 22lbs no matter how much boost it is actually pushing. At least thats what the tuners I have talked to told me. [/QUOTE]
