I need to some help. Ive noticed over the past few weeks that my truck will only build 12 lbs of boost at wot. I have just recently done the 6637 filter mod. I checked all of the intercooler connections and none seem to be leaking and all the clamps are tight. I have my boost guage hooked into the intake side of my boost fooler right before the map sensor. The line for the boost guage also checks out. Last night i had my good friend/mechanic hook up his versus computer to the truck and it turns out that my IAT sensor is not functioning properly. At operating temps it was only reading between 0-2 degrees F. Would that sensor cause the truck to not build boost? I have noticed that the EBPV has been coming on more frequently lately (temps have been in the high 50's low 60's) even in the afternoons when it has warmed up, but i am thinking that this is due to the bad sensor. I have a wicked wheel installed in the turbo and a 4" turbo back exhaust with no muffler. Back when i first installed the WW, i would easily see 28-30 lbs of boost. Any suggestions?
