Why u no tune?

Correct, stock location 3 inch inlet and no headwork. Some fellas on rexnet are making the same numbers as i am with the same turbo so im glad the numbers are normal not overly high.

GCP's dyno is inflated as my mate got his V7 tuned a while ago and put down ~220kw on GCP's dyno and goes for a dyno day on another dyno and gets ~190kw in same sort of conditions..

You guys are right about people trying to make their own cut on Link ECUs...Possum Bourne wanted me to get a Link ECU for my stock turbo and intake a year ago LOL...I think E H motors or Raijin would be good options but E H charge $1200 a tune..

Hey Kris, do you have a custom built Blouch 3071? I have heard that the Blouch 3071 and 3076 turbos are crazy in spool and power

The difference in dyno readings might just come down to the

a) Type of dyno they use whether it be the dynapack vs rolling road dyno, my personal take is dynapacks read higher numbers compared to the rolling road dyno because they are measured at the hubs not at the wheels and also they dont put enough load on the car match the real world conditions.

b) what correction factor they use - comes down to stp vs din vs sae. Majority of the tuners in nz with dynapacks use sae. Much debate as to which one should be used. STM, Sochi use din and most people seem to agree with this because it gives the lowest reading but you could make the argument that stm isnt the benchmark for comparsion.

c)how what gear they usually make the run on - On the dynopack its important to make runs on the gear thats closest to the 1:1 ratio. On 6 speed subarus i know its the 5th and 6 spd evos 4th. Like wise the 5spd its on the 4th gear for earlier stis.

d) tcf - must be left at 1. Anything more inflates the end result

Kingcole - I could just go as far as saying nobody out there rivals Blouch when it comes to stock location turbos on subarus. Their units are value for money, period. I make 22psi by 3600rpm due to the billet wheel and ball bearing goodness!! It may be just a touch laggy but when it comes on you better hold on hahaha.

I got one of my mates to record what my car sounds like from 2nd gear unfortunately he recorded with his ****ty iphone. *not promoting street racing*
