Hi

Pretty sure it's around the 14psi mark, unless it's the RC model which is 17psi 8) .

Cheers, Mark

It seems to vary from car to car but around 12-13psi is normal, only one way to find out :wink:

what model gt4? and from ur sig i think fuel cut would be the least of ur worries.start saving for clutches,diffs and gboxes :wink:
my st185 cut about 14-15 psi , st165 are similar as well i think.the st205 doesnt cut til sumwhere above 18psi i think. unless you hav an RC edition gt4 or st205 then dont bother with anything above 14-15psi consistently as the wee turbos like to fall apart.plus the ecu doesnt hav fuel maps above 14.5 psi anyway , hence the fuel cut :?

WRC ST205 has it's fuel cut at 17psi. Their turbos have steel internals so they don't crap out so easily :D

Not with the stock ecu, turbo and intercooler it's not. The stock turbo doesn't give much more power after 14psi anway.

aim for 14 psi.you will probly need a fuel cut defender to stop it cutting out on colder evenings.. if you are smart and hav a decent air filter and exhaust fitted already , you will probly struggle to get a steady boost level anyway , so by aiming for 14 you will get anywhere from 13-15.

Its for a MR-2 but it might be of some help.

This is a link to a site that is all about tuning the 3S-GTE, in a MR-2 but Im sure that there are no major differences other than the RC models and the differing ECU. Might be way off but worth a read anyway.

Lanius has a fmic on his, there's sweet fa room in the stock front bumper but if you upgrade to an RC bumper it allows for a lot more space up front but there would be quite an increase in lag, If I were you I'd try and find a water-air setup unless you want the bling factor.
