gen3 1ggte only running 9pound ?

[Jonno2002]

got my motor all up and running and installed boost guage (lame autoguage cheapy) only to find it boosts 9 pound, i was under the impression that these motors run 11 pound, its got grey ecu plugs and green injectors so all i can think of is that some previous owner has replaced the turbos with an earlier model ? sound right ?

is it intercooled?

[Jonno2002]

yes it is im using the factory ga70 i/c and piping which i managed to fit into my gx81 without modifying

Have you tried throwing the boost gauge in the bin, i had one of those in my 4x4 bighorn, it was reading 20 psi.... just cheap junk in my opinion.... 2nd hand autometer gauge off trademe now reads correctly...

[cat007]

just because the ecu etc is a gen 3 doesnt mean the turbo/wastegates are, which is what actually controls the boost.....

[strx7]

i see this on alot of vehicles. Wastegate gets its feed straight off the compressor housing where the air is hot, the air then gets cooled down and you have a tad less pressure because of that in the manifold which is i'm picking where you are getting your boost guage reading from.

Some of it is also boost guage inaccuracy

[Jonno2002]

thx we figured that out today, probably because the wastegates get their feed strait from the compressor housings and cause of the front mount.

and cat007 did u even read what i wrote, dont tell me what i already know kthxbye

Throw the autogauge away. The autogauge in the Zed reads 2psi on full boost lol

[Jonno2002]

probly got a hole in ur boost hose lol
