I am helping a friend with a s2000 build and the car just completely falls on its face when boost comes on. It wants to build boost but something makes it cut every single time. I disconnected a pipe on the intercooler just to see what happens and it just doesn't want to accelerate. Car is running injector dynamics 1300cc injectors and a walbro 450 with a rewire. The odd part is the first time out the car was fine.
Things I've tried:
Replace fpr for a known good one
Check wires
Replace fuel pump with a known good 450.

Here are some clips.

Thanks

 

I will look into tps and map readings tomorrow with my tuner.

 

Do you or your friend have any logs?

 

If you are running AEM infinity try reloading the map. This happened to me when i swapped ECU.

 

It ended up being a broken wire in the wideband sensor. Thank you everyone
