hi guys

i have been trying to understand more and more of the tuning side of things. i pretty much have the concept down ok and working along with a friend on tuning my e4 for the past few weeks and was just wanting to know what you guys think so far how it looks I have attached 2 logs and ROM. Is it natural for the turbo to spike to 230 load (18 psi) and taper off to like 190 (14-15 psi)?

Any and all recommendations will be greatly appreciated.

Thanks in advance guyz.

yes its normal for boost to peak and tale off if your still using standard boost control

its normal on the gizzmos.whats your gain and duty settings?

Take a bit of timing out of the top end of the map to minimise the knock.

Could get away with leaning it out a touch as well more than likely.

Also looks like it boosts a little bit late so might be worth checking the actuator is pre-tensioned correctly

Duty is set to like 50 and gain is set to like 20.

Hey Andy

Made a few timing changes and log a run. What do you think?
