Did we ever get a solution for this? I've got quite a few boosted toys, and I really enjoy having them all have them same blow off (Currently Tial-Q).
These electronic blow offs are just so stupid, and they don't sound good. I hope that these ecoboost stangs will get some of these real shops off their ass and develop some parts for these easy issues.
I am running the TiAL blow off valve for about 6 months now. Make sure you get the right spring though or it will be open at idle. I am using the yellow spring.
I'm very familiar with how a spring operated bov works. My questions were around where to acquire these "Hot pipes" (If anyone even made them for xsports) and if anything was done about the computer / codes.
I don't know whether they are made for the X-port... but on the transverse 3.5TT EB GDI engine the rear factory electric BOV must be left connected regardless of any mods or the engine will throw DTC and CEL regardless of tuning or how many time you clear it... the front can be removed. The hotpipes made by PPE for Ecopowerparts (now sold through Black market Racing) can be had for either factory BOV or Tial mechanical BOV. In the mechanical version the Tial VTA is from the IC to throttle body pipe In the electric version the Factory BOVs mount in OEM positions on the preintercooler hotpipes but are VTA with a large opening for the blowoff.
I am unaware of any dyno or track testing in the Flex or SHO showing one superior to the other as far as performance. The ease of use in tuning and amount of IC condensation of oil and fuel may be another debate. A catch can solution for the PCV/CC blowby is available from many manufacturers and there are numerous threads here on these.
I am running these hotpipes with factory electric BOVs without a problem.. I prefer the aesthetics (I have nothing under the engine cover just zip tied and doing nothing). and function is great as far as sound (I'm asked by other drivers what that Pffft sound was) and performance (0-60 in 4 sec or less consistently).
VTA, IMHO, is more than just the sound... if you recirculate the blowoff then you send the volatilized oil, etc. that you compressed (from CC blowby via PCV system dumping into the intake air) back for another pass over the turbo blades... This would increase coking of the blades and perhaps increased deposits...at least make it more rapid than VTA... and could result in more condensation in the IC. So I believe VTA actually protects your engine and helps preserve performance in the GDI... In the mechanical version the Tial VTA is from the IC to throttle body pipe... don't believe this location matters except that a catch can is more important if you're worried about sending a gulp of liquid to the engine and it is easier to access when you are changing springs.
