after put in the P600 turbo my car can't make any boost ECU tune is not done ye,the Ktuner map show it will run -9 PSI to -0.3 PSI is this about the ECU or the install
i have no code on my car i will go to the shop and seeWhen I first threw in the p600 I got a p0046 not sure if you did as well but that was causing me not to make any boost. The wastegate flap was stuck close because I had tighten the nut too much. Follow this WG Calibration Guide. Custom tune is highly recommended. Another tell tell sign is that your not hitting the commanded position which you can look at in data logs.
I get it was the Electronic Wastegate Actuator Arm I need to chage the OEM one is too longWaste Gates are Very Touchy , I Ported one ( Very Small Amount ) .025 ~ .030 with Larger Opening at Bottom where it comes from Exducer ( Exhaust Internal Wheel )
Near Center of Exhaust Manifold ~ Opened that Entering point , Like .062 ( Wow ) changed entire Waste Setting had to be Cranked Down to Build Boost . .
Took about .180 of sec. Longer to get Up to 23Psi , but Once there It Held Nice and Had much Better Top End 7200 Rpms where most Others were Falling Off at 6800rpm ..
I also did some Opening Up Boost Side - here's a - Before & After and a Polishing Inside Turbo - Before & After View attachment 8348 View attachment 8349
