Reduced Engine Power help please

I have a Magnacharged 05 Silverado 5.3l it has a 90mm T-body with an X-Link water/meth injection, heads, cam headers, dual 3 exhaust. I am running a semi OLSD COS3 with a 2 bar MAP sensor. I had a 2.9 pulley on it for a while, and it would go into REP mode a few times a night at the strip. It never went in until I was just crossing the traps so I just cleared it and went on with my night. I would get a P0102, P1516, and sometimes a P0106 code with it. I recently changed to a 2.6 pulley, and have been going into REP with a P0102, and a P2101 if I hold it at about 60-70% throttle. If I floor it, it will rev up, and often times go into REP with a P1516 and P0102 code. I have done a resistance check on the wires to the Tbody, and they check OK. I have also checked the ground wire to the passenger side head, and that appears to be fine.

I think you are exceeding the TPS, ETC or MAP rationality tables (look in the Engine Diagnostics folder).

Are you running a MAF...?

No MAF. Well it is in the inlet after the filter, but it is unplugged. I am running my IAT sensor where Magnacharger puts it in the intake.

The P1516 code is whats causing REP.You are supposed to get the P0102 when you have the MAF disconnected,SD mode.Check the wires going into the TPS................Paul
