Installed a FRPP monoblade on my 07 and took for a test drive last weekend. Probably went 100 miles, and then about a mile from the house car went into fail safe mode. Limped it home and checked the codes.... P2104 & P2112. The car would accept throttle about 10-15 seconds after it cranked, then go into fail safe mode again. I checked nothing last Saturday because I had obligations that night, and then was out of town all week with my job.

Fast forward to this morning. Car fires up and pulls out of garage fine. I hooked up an Autel 908P diagnostic scan tool and pulled the stored codes. I cleared them from memory, and took the car for a drive (20 miles) with no issues.... Drove great.

What is the likely cause of this? TB actuator or a TPS? Brand new TB and the tune was adjusted for the monoblade. Appreciate any thoughts.....

if it shuts off at wot its a tune problem ..if in normal driving gives you fail safe engine mode than its the TB actuator

Actuator, happened to me twice now.

The TB is new out of the box?

That's a surprise on a NIB unit.

I'm at a loss why.
