I have a 92 GT Turbo wagon with Blitz EBC running low boost at 10psi and
high boiost at 15psi and I have founf the facotry fuel cut on my vehicle to
be 16psi. I dont know what th fuel cut is for other models or type ra, rs,
gt etc but I figure that up to the facotry fuel cut there should be fuel
maps for th eengine from the ecu? I dont seem to have had any obvious issues
with the car running at 15psi on stock ecu, not that I run it at this all
the time but am still yet to chuck on a air/fuel ration gauge and exhaust
temp guage. Some please correct me if I am missing something competely
obvious.

Tommy.

Yes, and since you still need to raise your "boost cut", add a boost
controller such as the Hallman to the Map sensor line as well, so you
don't totally eliminate the safety of the boost cut, but rather raise
it to wherever you want it.

Tommy, that has always been my assumption as well. Granted, the
higher you get to the cut-off, the lower your saftey margin gets, but
as long as your under the cut-off, all should be OK....I would think
