It wouldn't boost anymore with that exhaust.. Its pretty old and rusty.. I'm happy with low boost until I get a proper computer.

ok ,still a top result for 4psi..
that exhaust must be super restrictive to stop it from boosting...

That makes sense....I had a blocked cat which stopped me seeing over 5psi. Once it was fixed 10psi was immediately available.

Massive power for such low boost! Must be a very efficient engine. You'll get some great results when you can turn the boost up.

I finially took delevery of it.. The numbers it makes don't even tell half the story.. This thing flys.. Honestly feels closer to 300 then 230.. The c10 is fun to drive aswell

after over a year of continually trying to get it right at mikes dyno tuning iv gave up.. i cant strongly enough recommend enough that no one with a i6 go there, he is an absolute prick, with possibly the worst service i have ever gotten in my life.
iv returned there over 15 times with repeated problems that a brand new motor should not have, only to find that the same problems existed when i left his workshop.

ive replaced the entire rocker gear myself and it seems okay for now.
on the cards for the next couple weeks are a 3 inch mandrel bent exhaust with magna flow mufflers and a 3.5' cat, remove batteri to boot and set up a proper cai with heat sheild, redo the ugly cooler piping i have and have it as short as possible with mandrel bends, custom accelerator cable to stop the turbo heat from stretching it, fit a oil catch can, and retune it with a microtech lt-10.
should see a 300rwkw pretty easily.
some of the work is being done myself, and the harder bits by Anthony Rodrigues @ maztech. my experience with his has been nothing short of exceptional, he is a whizz in tuning microtech's and my only regret is not taking it to him sooner.

Nice feedback mate, looking forward to seeing some further results
