Boost Taper
I have a 2016 EWG n55 FBO PS2. ( stock inlet )
GFB DV, 93 octane. 750cc injectors. Custom tuned. ( checked maps of 2 tuners ) Less than 15k miles. ( weekend car ) The issue is what the title says. Boost tapers as the rpm goes higher. The wgdc says around 100. No throttle closures. Timings are fine i guess. The HPFP is quiet happy. I have done a 25psi air test. ( no leakage ) Done with a smoke test. ( nothing found ) Diagnosed through ISTA. Have a look at the logs, pics and guide. Thank you https://www.bootmod3.net/log?id=6381...90c6e22f6d46a3 https://www.bootmod3.net/log?id=6381...729b3ec75e4a38 https://photos.app.goo.gl/LAupzRVjZWCYT4o39 Seriously i am fed up past many months 😑 Help please.

have you tried any of the OTS maps such as the stage 2+ 93 (assuming you have upgraded your hpfp). otherwise you could try the stage 2h map.

Did you check with PTF?
Maybe your turbo is bad.

PTF says to check ewg and dv. The car isnt showing any codes but i am checking the wastegate again just for satisfaction. Got the turbo from you people 3 weeks back i guess. Once i check the wg and dv once again than i,ll check the turbo thoroughly. Last edited by Zinia; 12-02-2022 at 02:50 PM.. |

i did a stock tune wot log today just to get some idea that maybe we can norrow down our problem. The wgdc is not 100 means the wg is working. What other clues do we get from here? Kindly help.

Hello
I installed an upgraded inlet pipe. I think the wgdc and boost taper issue is much better. Please advice. https://www.bootmod3.net/log?id=639c...0b43c619bfc96b |
