Running KU31 255/30/19 on the rears

A little box slip, which is why the rpm is out - redline set to 7k.

Cooler was a little heat soaked after 30 something runs, and tuner wanted to play with extra load points at the bottom to fix idling.

Could have pushed for 300@20psi, but it was overall too laggy to be my daily and tuner had concerns over bend shaft causing rear wheel to touch the housing.

Decided to ask Stao to resize from an ATR34G3 to an ATR34SS2 to improve response.

Since then there's been some box troubles, so have replaced the solenoids and upgraded 2nd gear to a billet servo.

New tune *hopefully* next week, will post results then.

Stock internals, stock injectors@ 90% duty cycle, stock afm

Power = 245rwkw @ 162kph & 509nm @ 124kph

Boost getting up to 11psi dropping to about 8psi by 7500rpm need to get a 10 or 11 psi actuator and piss the boost controller off

Im sure iv missed some bits

Tuned by Brent at envydyno

338rwkw at 22psi

varex was a bit restrictive

afr's in the low 11's high 10's

full boost by 5000rpm, peak power at 6000 rpm,

over 8000n of tractive effort

I will eventually do cams and get a smaller exhaust housing and electric boost controller so i can get boost hard by 4000 rpm hopefully.

And the best bit, all legal! everything is engineered.

Iv set it up for track days, hilclimb and occasional drag day. All for fun.

I will post a graph when i get to scanner :-)

Can anyone with and input/info pm me please

Here is my sheet for my previous post I cant edit it onto it?

The dip in the top end is from my exhaust, all 3 inch but wastegate is plumbed and I have a varex, which is a but undersize... afrs deliberately left very low at very top...

740cc injectors (high flow)

peak boost around 17psi at 5,000rpm drops to 16psi at 6,700rpm

injectors playing up so did not raise boost not a lot of timing.
