So you have an aftermarket guage and factory one?

could be a few things, both wastegates stuck open (not sure why that would happen)

big boost leak (but then car should run rough as it will be running very rick when losing all the air after the afm)

if they are ceramic turbos the exhaust wheels could be shattered?

what mods std afm and computer system?

yeah an apexi and a stock guage

both needles dont move a bit no matter how you drive, and even at idle.

ive had a leak before and the car ran like shit and usualy stuff comes out the exhaust

they're n1 turbos and the boost has never been overboosted to a dangerous level

usual mods

cooler

ebc

im just stuck to understand why the guages sit at 0..

well then have u checked where the guages are connected? if they read zero at idel something definatly wrong. are they plumbed in independantly?

you will have vacume at idel, if the guages have disconnected then they see atmospheric pressure and stay at 0 at all times.

i'll go check again now, but they all end up in the same spot near the firewall drivers side.

    • Install a MAP sensor pre and post throttle. Best data you could have for NA, then play with the bends and/or air box and see how much of inflection is created at WOT on the plot.
    • The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.
    • Sounds like the oil pressure light is wired into the oil temp sensor... As it warms up, resistance on temp sensor reduces, hence more current can flow and the dash light gets brighter.
