Boost Psi Issue!

[WOG BOY]

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)

i have an aftermarket boost gauge...

i have heard/read bout the 4500rpm cut in thing, but it still doesnt reach it....

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
