After a week of ordering parts that didnt come with the "kit" my buddy bought, I finally fired this his truck up yesterday with what I thought was a good base tune. Within about 20 seconds it seemed something was way off as the IAT climbed past 105. The MAF/IAT sensor area of the intake tube was cool to the touch and only show 98 with a temp gun. Then I noticed the boost valve was closed at idle and opening with throttle. I am hoping the boost valve is the culprit for both of those issues, the idle never doing anything other than -30 degrees of timing (even after pulling 100ft/lb out of it), and trims over 35% no matter what. IAT ended up at 156 while ECT never went over 160.
Needless to say my buddy wants his truck back. Is the IAT relocated to the LT4 MAP sensor with these setups? Should MAP sensor be NA-MAP instead of NA-TIAP? I copied the map estimations and characteristics from an LT4 car so I assume those to be correct.
