v6 to v8 swap , pretty straight forward plugged right into fuse box the engine harness .
driving normal is fine , after at stop sign and stomping it wot or more half throttle ., before it even comes up to high rpm itll loose the throttle , and ill have to let it glide over to side of street , key off wait few minutes then back to normal . It only happens here and there . not constant .
Truck is open loop , o2s turned off . Running maf . Any ideals . i could log a run and try that. Maybe faulty throttle body?

 

 

Hey man I'm glad I finally found you I need to ask you a couple questions about the motor that was in with the single turbo

 

I think posting the tune would be a good idea. My guess is it goes into limp mode when the expected airflow is greater than the actual calculated airflow. It is a common issue with speed density tuning. Hopefully someone more knowledgeable could chime in and explain better than I can

 

Any codes?

 

What throttle body is on the V8? Gold or silver throttle blade? I've heard of WOT issues when using the wrong one - I believe the correct throttle body for the 09+ cars is the gold blade. Just another thing to check out.
