Working with Torrie at Unleashed Tuning great experience thus far in tuning my SC 4.0L Sport Trac. He has tuned my W/M injected Taurus SHO with amazing results. One of the best in biz but that's another discussion.
I have swapped to a 90mm MAF housing and Lightning MAF. Torrie has it idling, driving, accelerating and shifting very well at 4.4psi peak on a 3.5 moddbox pulley (blower was ported) However, I have a P0113 IAT sensor 1 circuit high bank 1 CEL and the datalogger shows 76 degrees constantly and need to figure that out prior to moving foward and moving to MB 5.5 psi pulley.
Is sensor 1 integrated into the MAF? Anyone have some ideas of where to start troubleshooting this issue?
I plan on moving back to a pre-L MAF tune and re-installing stock MAF and housing to see if CEL subsidies. If so the maybe an issue with the MAF itself.
What else can I try or look for?
