I have a 01 a4 that has a k04 with stage 2 revo I'm running a mbc because I had uncontrollable boost spikes well now that is fixed but I was have throttle cut issues so I used a 4.3v zener diode as a throttle cut defender but now once I get above 5k instead of cutting and falling on its face it kinda surges and I'm running my mbc in parallel with the n75 need help this happen to anyone else

what do you have the boost set to? it still might be too high. i have mine set to 23 pounds and my injectors are at like 115% duty cycle last time i logged and ill still get throttle cut. but if i turn it down it runs fine.

I was running 18 before I put the diode then I tried to run 20 but it surges real bad its worse than boost cut not enough fuel?

I am having the problem that you had, with the boost spikes. I have the same set up that you do minus the throttle cuts and the diode. I have an MBC on the way just not sure how to hook it up to run it parallel with the n75. Can you shoot me a diagram on how you hooked it up?
