Hi guys, Have recently got my car tuned up and all sensors replaced. Tuner gave me a list of things to do have done them all 100% no half ass **** As I bought the car raped. Seeing tuner in few weeks just wanting to tinker and learn something for myself . Car thinks about stalling after boost (12psi). And when I give it a boot full and come straight off it sometimes stalls. I have an aluminium air box surrounding pod with AFM (similar to original) And yes the car has an intercooler. I have welded a BOV venting to atmosphere Close as possible to the throttle body ( to stop the compressor surge) as in my opinion could be messing with the AFM. BOV could need adjusting. And don't really want to relocate the AFM some people say it helps and what not. Just wonting to see what other people have done in the situation and I know people are going to say CAS but it's been tested. Please could some one give me some useful knowledge and share there experience Cheers guys Some original photos have not been recovered yet.

If it was my car then BOV into the bin! I know you have already said it but I had the same problem until I put AFM into cooler pipes!

Thanks mate for the reply. Just done a lot of work engine bay looks really neat. Don't want to go cutting the piping :/ It could be the best thing but there is always someone on the internet telling you different lol. Some original photos have not been recovered yet.

BOV - remove it you are metering air, then dumping it through the BOV, so you are dumping a whole lot of fuel in, and not enough air

^^ this is spot on, not much more to say. same with what deano said AFM in the cooler pipes. i can't say much more ahah

If I was to plumbing back my BOV where abouts ?? I fitted it because i kept blowing the ass out of my AFMs. Onto 3rd now and it has defaffanty worked. And photos will help thanks guys I'll try and post some pics of my setup if I find out how to Cheers

what ecu are you running?

Stock turbo ecu. Stock AFM. Cars running well other wise
