wouldnt bother, if u want more power then increase the boost.
BUT i tried it on mine from 10psi to 18psi or so and there was minimal improvement.
at the end of the day its still a diesel not a race car.

when you cranked your boost did you have to wind more fuel in or is it handleing it ok .. did it blow much more black smoke with that much more boost ??

mate thejabber isnt on the road anymore.
when i was driving it regularly i used to fill up every 500ks and it was around the 50lt mark on average.
i got anywhere between 8.5 per hundred to 14 per hundred depending on how i drove it

I have the same engine as you but in a gen1
I also have 33" tyres.

I think this combination is just slow.....
accept it, winding up the fuel or overboosting is asking for trouble.

J-top Paj- no longer has his on the road, I think he was maybe looking to part out? his has 5.29 ratio diffs (I think) so this would be a better option to compensate for low power larger tyres.

Did the straight through exaust help the power economy?

I have heard about the turbos needing replacement (hearsay) but don't know of anyone who has owned one actually have to replace a turbo.

not sure about parting it out yet... and if i do someone else has already got the diffs,
i heard about the 100k turbo thing too but im not convinced.

the zorst did help a little but its still a little diesel pushing 2t worth of truck so dont expect much.
the 5.29s do help a lot tho. when my mate had his 2.4l surf we used to have a bit of fun at the lights now and then and i was in 3rd before he got to change from first to second :lol: and i was in front all of the time too :D :armsup:

How do you wind up the fuel & what is a good indicator of how much or how little fuel is being used.

im not 100% sure myself but i have been talking to my mates neighbour who used to build up pajeros and he sez u need a boost gauge and boost controller and a pyro gauge and u tune it off the temperature of the exhaust apparently
