2014 Ford Raptor Roush SC stall issue
hello
A couple of years ago we bought this kit Roush part number 421432, and installed into brand new truck with less than 1.000 km on the clock
the Raptor now has 35.000 km .
VIN is EFB65410
It has also long tube headers by KOOKS
Customer complaint is engine stall.
At warm engine, on turnabout
It happens very rarely, let's say once every 2 months, But it's very dangerous.
No DTC on the system
Throttle body was just a little dirt, and concern can't be duplicated.
someone has already faced this kind of issue and has some experience to share?
thank you so much
best regards

I have the same issue did the ECM reflash per Whipple and still having the same problem I drilled two 11/16 holes in the throttle body plates and still have the problem anyone have any other luck with fixes seems like throttle is getting closed to early or too much

Your torque tables at idle need to be adjusted, along with driver demand at idle.

This is super common on the 6.2 raptors with longtubes. It's a fueling feedback issue. You need to adjust the proportional and integral gain tables most likely to stop the overshoot fuel correction which is most likely causing the stall
