I made a new intake for my LB7 and decided to go without a MAF so that the intake is easier to remove for teching the turbo at the pulls. I don't drive it on the road a whole lot or tow anything so I don't really care about having the MAF on. I turned up the MAF Limiting tables and disabled the codes for MAF. I tried it out and got a P0113 code for IAT sensor high, I forgot about that sensor being part of the MAF. So I went to change my tune to compensate for the IAT sensor and I want to make sure I did it right. I turned of the codes for the IAT sensor, but I am not sure if I need to change anything in the tune as well. I looked for everything that had IAT in it, I saw the intake air heater and turned that table to 0 because I also removed the intake air heater. I saw there is a table for timing and IAT, but the whole table is set at 0 so that doesn't appear to actually be doing anything. There is also another table for IAT multiplier, I think it said it was for desired boost. Do I need to do anything with that multiplier table or timing table? Is there anything else that I missed? The truck seems to run the same as before, I just want to make sure I am not hurting performance by limiting something. Thanks in advance.

Working on the same thing

yes zero it out. . and turn off the mill lights and the tests for the maf sensor

I am in the process of doing the same thing. I added a seperate IAT sensor in the charge tube going to the engine so I can monitor the air temp after the intercooler. I disabled all of the MAF tables & it started & idled fine with no check engine light. I just drove it for the first time today & it won't accelerate hard. It feels like anything past 50% throttle doesn't do anything. I haven't put the scan tool on it yet to see if I can tell what is limiting it. I must have missed a table somewhere. Any thoughts?
