Looks good. However I wonder what the slight boost dip is that you have between 4000 and 5000 rpm. After 5k rpm it seems to pick up again. If you mail me the csv i can have a look

I think the dip is the turbo struggling because im started the log in 4th gear at a low rpm I could be wrong. I'll send you the csv tonight when I get home

I think the dip is because he goes over target just before that at 4k. Boost looks nice and smooth now and holds nearly 17psi at 6k on the 2nd log. Huge improvement over stock!

Could be that maybe I'll raise the target up to 20psi I had it at 19.5 to play it safe but it does overboost to 20lbs for a bit. Could be because its trying to get back into target which is why it drops boost although I doubt it because even on the daily map it does it. I'll stay with my theory that its because I start going wot at 2800rpm in 4th gear so it its struggling to get up there

Great numbers - but it looks like a huge loss in low end power. Do you feel that on the road? Although at 3500 rpm, it must feel like you hit the nitrous

Any stage 1 turbo will show loss down low because you clip the turbine. But i dont feel the difference. And to be honest its probably for the best. Before i had no traction at all in 1st and most of 2nd and thats on RE11 which is a good tire. The gain up top is so worth it though.
