Dyzzii

Hi guys So my 03 STI is running a full set of DEFi Gauges (Boost, Oil Temp, Oil Pressure and Water Temp), but unfortunately the control box has two broken connectors, meaning that I can only get boost and water temp to work However my research has found that Rallysportdirect sell the v2 advance Defi Control Unit. My unit appears to be the V1 unit, and i'm struggling to figure out if my gauges are going to be compatible with this unit if I purchase it? Is anyone able to shed some light as to whether they will be compatible or not?

Are you referencing to batburmans?

Heres the boost curve: http://imgur.com/a/ChNBb For some reason it wont let me just upload the photo to the site

Yeah they did! Glad I found this place haha. Seems far more useful for information! How the hell are you pulling 867nm of torque!! That's ridiculous! Yeah I have my dyno sheet which shows my boost curve etc. It peaks at 23 and then drops right down to around 16psi at the end of the rev-range which i've been told is normal. Also thanks for the invite to this page! Seems way more reliable than a bloody fb page haha. I may put up a photo of the sheet just to show what it's doing Yeah i'm running a front mount to stop that haha. I just need to stop being lazy and get myself another window washer jet so I can relocate it to the front bumper and squirt from both sides.

Hey guys, just had a question about my boost level on my 2003 STI. Car is currently running 23.4PSI peak boost, which just seems a bit high, or is it safe? Past research leads me to believe around 21 is the highest you want to go. It drops down to around 17-18 across the end of the rev range however. Is running the stock JDM VF37 Twin Scroll Turbo. Is tuned on 98 octane running the following mods: - Front Mount Intercooler - RAGE catless downpipe - HKS mid-pipe and tip - DW200 In-Tank Fuel Pump - Apexi Air Intake Kit - Link 3-Port Boost Solenoid Tuner has told me the car sounds fine and is not struggling under boost whatsoever, which is why he set it to this. Just have that 21 figure set in my head of the highest safe number. Should I ask him to lower the boost level. He is a very reputable tuner and has tuned hundreds of these cars, just it has me worried. Any information is appreciated!
