Do you guys running this unit see any spike silimar to the n75. Just wondering as i'm fine tuning my car. I still feel like it is slower than it was before, but will be going through all aspects before i take it back for another reflash or checkup from giac. My peak boost is 21 then drops off to around 18 then drops off even more up towards redline. but 18-19 psi seems to be held more constant. the guys at turbo xs say there shouldnt be a big spike.......i just dont know this time.

 

If you have spiking issues, you need more bleed. Drop the psi down 2 and then turn the bleed up to make up that 2. If i remember correctly, you have a ko4-001 which is basically a spike high and fall off turbo, in that case, a mear 2psi spike isnt anything much and can also be written off as a difference in load if it only happens now and again
