My bad i thought you ment raise psi not check.Ive got a pfc hand controller i havent tried to check as tuner said it was set at 14 psi.But there must be a way you can check surely il ask tuner next time i see him.you havent had any knock issues with gtr have you?high knock readings on hand controller mine just does it on the random i dont understand why its doing it.

Hello Nissan owners Right im after some much need help i have an r33 with a rb25det built motor done 3500ks.Has a power fc im having high knock readings at about 5500 rpm 3rd gear engine light will flash my tuner said its false knock as it was only happening in one cell.An he advanced an retarted timing to check but the knock was still the same.He seems to be a good tuner an tunes Rbs on the regular. Heres the sequence start car knock max reading of 7 driving normal change before 4000 rpm max reading 14 thrash car 2nd gear 6000 rpm max reading 88 thrash car 3rd gear 6000 rpm max reading 97 now i can take it t past 6000 rpm to 7600 rev limit an engine light stops flashing knock reading doesnt get higher. I cant hear any knock or pinging an tuner said the same he triple checked that it would be fine so he said But what would cause this?Is it false knock have other people had these issues i dont wont my motor to detonate.Its a worry an dont want to thrash the car anymore until problem is solved any help would be much appreciated cheers

I would get it tuned on the dyno an raise the boost pressure that way then you know its not going to lean out.if you raise it manually its not tuned for that right an might not like it a hell of alot.upto you your gtr but that would be safest id say.
