Can I Check My Boost Psi From Apexi Controller?

[shanoplata]

Hello, I'm new to the forum and have had my R33 GTR series 3 for about two years now. Cars has run well and is running a conservative tune of 212kw at the wheels. My question is how can I check the boost pressure? I was a mechanic 10 years ago and am pretty savy with engines but have very limited experience with turbo charged cars and the thought of running too lean scares me but a bit more boost I think would be nice as 212kw does not thrill me anymore.

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.

yeah i hadn't considered attempting to tune it myself but I would like to know what pressure I'm currently running at as I havnt had it tuned since I bought it and forgot to ask to guy I bought it off what pressure it was at.

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.

I havent had any knock problems that i'm aware of but I've only looked on the controller twice since i've had it, I live 5-6 hours from a tuner and work a 7 day roster so I havent had it tuned since i've had it but it feels like it is straining at the moment when I start to get above 5500rpms so I've been cautious over the last couple of months. I would appreciate any info on checking psi as the turbo set up is pretty new to me. I didnt start it for about 6 months straight and the battery was so flat it was thrown out, I am also wondering whether it is possible in a case like mine that the memory battery in the apex ecu could restore to default if no power was run through it for a long period of time like that.
