I'm currently Running 1.4 mls headgasket and arp head studs ,The turbo was upgrade it ct-26 to 57 trim. Has front mount intercooler with piping and hks bov,k&n intake, 3in full exhaust to turbo, test pipe. Its giving me Codes 34,24 (24 being Intake air Temp Sensor Signal and 34 Turbocharger Pressure) Now where can i check for both of them and get them fixed? Thank you for your help.
Mk3 Supra 90 Model, Spitting codes of 34,24

Replace the 57 trim with stock, that gets rid of the 34. Test the thermistor circuit for 24. And since the ground is shared E2, (clean ground), that leaves two choices for you. And one of them isn't the ECM.

^Fuel cut would be my guess. Especially with the CEL flashing when it happens.
34 is abnormal turborcharger pressure. When the fuel cut happens, this comes with it. The T4 compressor wheel is the source. Now you have to work your way around it.
The Lex Meter with 550's is probably the lowest cost away around it. Not the best, just the lowest cost and easiest.
If you're hitting fuel cut at 2000 to 2200 rpm I want to know your secret. With my 57 I dont't hit full boost until about 3k. If you're serious about doing the lexus/injector job, do a lot of research first.
What psi are you hitting? Mine hits 8 psi with stock downpipe and borla catback. I'd remove anything like shims/boost controllers til you find why its hitting fuel cut so low.
Well i just went for a ride and forgot my cellphone..... But i just got my car back from the shop and they took off the test pipe that ran underneath, The before and after of the stock downpipe and the test pipe its a bit choppy with the 2nd gear on the stock downpipe but with the test pipe its a wide powerband with no fuel cut as well. All and all the stock downpipe kills 1st and 2nd gear but 3 4 5 smooth sailing, as for shims i don't know if the owner before me put them on.. so i wouldn't know where to check for those.
I wasn't even thinking about 2200 rpm. You probably have a leak between the air flow meter and throttle body. Don't buy a new air flow meter. Until you test it and the circuit for that 24.
