Stock Wastegate boost pressure and bleed valves.
Hey guys,
Have done some reading over the last few days regarding Boost pressures and have resorted to creating post. (apologies if this has been discussed and you guys know a link that I couldn't find.)
Firstly, I have had some issues regarding boost inconsistency in my 3 MPS
Mods:
3" Turbo back Exhaust
XEDE piggyback ECU
Custom Tune.
all done by the first owner (i'm the 3rd)
Having some issue with hesitation and misfiring at high load/revs/boost (20psi) and want to reduce the boost until I can get someone to tune it.
I'm in discussions with ChipTorque (who fitted and tuned) to get it baselined again and a re-tune but it will be a few weeks before I can get it to them on the Gold Coast.
My Question is, What is the Stock boost pressure of the wastegate? I know the stock boost is 15psi (thanks to this forums previous posts) but what about at the gate?
Second, and recommendations on manually boost taping? as my current "tune" has boost on Avg at 18psi
Can I manually bleed it to a safe say 12psi without both the factory ECU and piggyback chucking a wobbly? or even just run the stock wastegate pressure?
If so on any of the above whats "Best Practice" when adding a manual bleed? ie: off the front of the gate inline into the turbo inlet? or from the back wastegate port inline to the compressor housing and then do you leave the factory boost controlled connected to anything or just blanked off?
better yet is there already a post on how to do this?
sorry wall text post, have a lot on my mind and need a starting point and all these questions keep rattling my brain
Cheers
