I'd say stick to running near the MAP limit, and get some good timing.

Well, this needs 5120 or a "near map limit" tune, yep.
Decrease LDRXN by about 10-15 points and that should bring you to "measurable" boost levels.

Check ps_w. By some lucky coincidence it's juuuuuust riding the limit. So, AFRs remain fairly normal.

req boost is well below the MAP limit, which is why he's seeing throttle cut IIRC.

so he really needs to INCREASE ldrxn and cut a ton of WGDC

Thank you everybody, I will try a few options I'm going away for the weekend won't be able to test pilot till wednesday, also I think I may swap a oem wastegate on this thing because the cracking pressure is higher, no matter how I adjust the preload.

Meh, my bad indeed. Was looking at the rlsol_w when I wrote that (which is well above rl_w) - and completely forgot the fact that pssol is pretty darn low.

Try it "as is" with a stock wastegate and check where your requested and actual boost pressures are. Then start playing with boost PID as outlined in the wiki.

here it is, i adjusted the wastegate quite a bit and now boost is much more under control(too much of a pia to swap for oem). spiking and holding 25psi thru the mid range and tapering to 15psi. most importantly no power/boost cut. car rips i think its time to get out to the drag strip for fine tuning im not really comfortable on the street doing long wot blasts...

Still a bit of a hot mess.

You have a HUGE deviation post ramp, you'll still possibly throw limp.

Get req boost closer to map limit, also, your IMAX is proably way too high, your wgdc is really screwed up.

I did see a few things I wasn't happy with but for only adjusting the wastegate I'm happy. I only had like 20 mins free today. I will adjust the file tomorrow to get things aligned the way they should be or at least closer.
