So far after 2 hours mapping today on an AUM with a k03-k04-023 hybrid we have got 260bhp/292lbft...

The limiting factor was the stock k03 actuator which was old and weak and maxed the n75 out to 100% and 222bhp 250lbft,  boost peaked to 18psi and just fell straight off even with the N75 map hacked to 100%.

I had to make a make shift adjustable spring contraption to add pre load to the oem actuator until we car a forge unit with yellow spring in stock.   
The 260bhp was carried out with stock AUM injectors @4bar, which maxed out at 6300rpm on the 260bhp run.  My 386cc BAM injectors are going in tomorrow and another 1 of dyno testing to set the timing up.

I think I will easy hold around 18psi to 6500rpm....    I hope the final numbers to be around 270bhp/280lbft if we can run enough timing, only issues is the small turbine which produces high EMPs which passes heat back in to cylinder 3 causing timing pull.

that sounds great nick i would love a turbo like that so stock aum injectores ran out of puff at 260 and 250bhp would be safe or would the 260 be safe for road use?? how much to build one of these mate im looking at changing mine soon as doing clutch and flywheel only thing left if blower?

cheers
