Hitting fuel cut with stock engine @ 0,7 bar (boost pressure not adjusted)

[scotty]

Hi,

I'm hitting fuel cut max boost, aprox 0,7 bar. Engine mods are only 3" straight pipe, hks ssqv, arp studs, 2.5" intercooler pipes. No boost controller.

Turbo was just overhauled by a specialist company, so it's as good as new.

What is the fuel cut limit on stock AFM/injectors? Do I have a boost leak?

If i remember corectly, 0,7-0,8 is the limit on stock ecu.

0.7 bar = 9.8psi

That's right around where I hit fuel cut as well on a cooler day (around 65F or 18C). I might get up to 11 (approx 0.8 bar) but it doesn't go much further than that. On a warm day (around 80F or 27C) it will cut closer to 12. It does very much change with the air temperature, so keep that in mind.

If you do want you can try and find a boost leak, but if you do have one it's going to be very small.
