Third gear if you do a pull at 2500rpm it will do a strange noise similar to surge but it dosent affect the performance of the car. Im tuned at 26psi... i dont know if i have to buy a forge bvp and put the harder spring too... it is possible that the stock bvp leak at 26psi on k04r ?

Sure... i just want to know if i can resolve this problem... because its very easy to do some extra damage for my new turbo .... just to put the gaz pedal to 50% in thirs at low rpm and the tuebo do the same thing

Adjust the tune, thats how you resolve the problem likely. It's hard to say from a keyboard no where near the car or a log of the car running. If the sound happens when you give it 50% thottle at 2500rpm it's likely because the tune is calling for all the torque at part pedal to make it feel faster. I'm also assuming that at half throttle you can't keep it below 20psi and the throttle feels like an on off switch.
