Whats the standard boost pressure for a standard Zlet?
I've just fitted a boost gauge and wanted to check
was informed its 9psi
yep it's 9 for sure
mine was only boosting around 6psi as well but had actuator altered, so went bk to normal 9psi, although wk later i had a remap, so was pointless really,lol
Definately 9psi..... You may have a leak or a knackered turbo.
Arden Astra GSI - Phase 3.5
EDS Phase 3.5 288 BHP 340 FT/LB
Inlet cam and Dbilas manifold.
I hope it isnt a knackered turbo!
Only bought it 3 weeks ago!
Its a 2001 Coupe Turbo.
Something worth mentioning here, When i came to fit my boost gauge earlier, the fuel pressure regulator wasnt connect, the rubber elbow was on it, but the vac pipe had fell off.
I reconeccted it, but it didnt feel any different.
Dont know how long it had been disconnected for....
