Hi all, not entirely sure on whether this is a mechanical fault or it has jus been tuned really realy conservatively/safely...

No matter how hard i try, i cannot get my BOOST PRESSURE over 5psi...on the boost gauge the needle only points up to 5 but can/should go higher...

i was under the impression that the stock tune was up to 7-10psi....so yeah, i was wondering if u think it may be tuned this way as an 'ultra-safe' tune or what?

also, what can the stock parts handle? 10psi?

was goin to get it all serviced and tunes in the enxt fortnight so if i can have some answers and ideas it would be great!

Cheers

Matt

5psi low, 7psi high (after 4500rpm or so in 3rd gear) is normal. Are you looking at the stock gauge (which doesn't read in PSI on 33) or another gauge? It's possibly the stock boost controller isn't plugged in at all, and the wastegate is connected directly to the intake.

Safe is around 12psi (though you'd probably be hitting R&R by then)

The only way to check out is by using a boost controller and boost it to 7 psi to see if it reaches that....cuz if it doesn't reach then thats a problem...

Dun think R33 should go higher than 7 psi without a front mount I/C...but u can go up to 12 psi safely with a Front mount I/C :P

      Just to be clear, there were no lights or codes when the hiccups were occurring. Also nothing noticeable in the cars' braking. It brakes fine and the dash is clear. I only made the connection when it did throw a code and suddenly, despite the lights, it felt great again.

      Yeah they are sliders and this was in my head before I worked out it was the speed sensor.

      Ok so we have a smoking gun.  A few weeks ago I had to replace a speed sensor that I'd fit incorrectly. I replaced the sensor and everything was fine with no lights or codes thrown any longer.  When I was doing some more bedding in yesterday I got ABS and traction control lights again and, considering when this happens those things are disabled, the pedal went back to normal with smooth braking and no hiccups.  The codes thrown are for the same speed sensor that I replaced. When I looked at the sensor I took out it looks like the tip of the sensor is damaged. So whatever happened to it, perhaps it has damaged the magnetic ring on the bearing (that I only replaced the other week). I'll get my boroscope in the hole where the sensor goes and see if there is any damage in there. Hopefully just the tip of the sensor is in there and the bearing is fine. 🤞🏻  It's worth noting also that the pedal hiccup happens more often and for longer periods now and totally goes away when the codes are thrown again which happens usually after 5 or so minutes of driving. Love all your help here as usual guys, thanks!

      Could you put a real seat and harness in instead of what looks like leaving your passenger balancing on a milk crate
