APS twin turbo problem
Hi,I have 2005 european version of 350z and I bought a APS TT kit . It is already installed , I was at dyno last week . They found out that I have 350 HP ,295 lbft ( before without kit : 274 HP , 243 lbft ) . The power is not so big as it could be , and the curve isn't linear . See on the graph . Do you know where could be a problem ? Thanks for ideas

what type of boost control?
what boost level are you seeing?
pipni -
Is this the tuner kit?
If so, is it a newer version with the journal bearing turbos?
What engine management are you using?
What size injectors?
This is very important to some of us with this kit.

Jay - is that the appx rpm where your power fell off a cliff? I wonder if what we are seeing is the "choke point" the guys at Blouch were referring to when they told me these turbos would likely stop producing power before they met their max hp rating?
Is that Torque # right in the graph? If so, I need someone to explain it to me please.

It would be nice if other vendors/dealers could post the new APS POS dyno's too
