what you guys think?
Went to rollers and these are results

1293cc , 18cc omegas, gt1752, phase 2 cam, Benross head...
Starting with low boost, enough time to power it up when its run in....


First run at 6psi second at 11 psi

Personally i'd aim for a slightly lower AFR as it's spooling up and around peak torque but that's just my opinion. Looks like it's makes good power figures to me!

(second run)

look like what i would expect from a standard turbo needle running 5 and 10 psi

i would like to see more fuel in through the entire rev range and a little extra a bit faster down low,
i had a similar problem with the GT20, it would boost straight up to 15psi in an instant and allowing the needle to fuel for that is tricky, the speed the GT17 spools is the same ( give or take)

Yes i moved to the darkside

So you guys prefer a sharper needle??

i would rather have the correct needle, mine was something like 0.65mm at station 11 for around 30psi boost

i did have a huge spreadsheet of about 10 stock needles and maybe 20 needles i made

unfortunately a couple hard drive failures withing weeks wiped out alot of my info :(
