Cant hit target boost, ive tried everything !
Hi Everyone,
Id really appreciate some insight if anyone has any as im straight out of ideas and becoming frustrated with this platform. Ive been trying to find out why i cant seem to hit target boost for what seems like the longest time. Here is a quick run down on my mods and what has been done to try and fix the issue. Pure stage 1 (brand new) Relocated Inlets 7" HD VRSF Intercooler Chargepipe MOTIV Custom Tune 91 octane Turbosmart BPV's Some maintenance items and fail safes i just recently completed. Brand new Solenoids Brand new vac lines Ensured waste gates arnt touching the downpipe v band Just last night took all my cold side piping apart and put it all back tight as can be. After all this, i still cant hit my targets, here are a couple data logs. if anyone has any insight i would much appreciate it, or what i should do to try and solve this problem. thanks in advance https://datazap.me/u/stealthbombing/...og=0&data=3-21 https://datazap.me/u/stealthbombing/...og=0&data=3-21 Here is a 5th gear mini pull, for some reason half throttle i come closer to my targets and my WGDC isnt maxed https://datazap.me/u/stealthbombing/...og=0&data=3-21 Last edited by Stealthbombing; 05-31-2019 at 02:06 PM.. |

This may or may not be related to your boost target issue, but it was something I noticed in your logs that you may want to look into:
IIRC fuel rail pressure should stay above 1800 psi during normal operation. Yours is dropping to ~1200. You likely need an upgraded fuel system to keep up with the demand now that your new turbo can provide more air.

...and I don't think you should not be doing pulls in 5th gear. Use 3rd.

Okay i found my leak, its leaking where the Chargepipe meets the Throttle body. I have the phoenix racing CP and when the system is pressurized if i wiggle the chargepipe a bit it leaks. Do the O rings go bad ?

It's the same O-ring as the large one on the oil filter holder I believe. It sometimes gets lost/sucked in during install.
