i'm running an s4 tii engine with stock s5 turbo. i've been reading the instructions for this thing, and it's a bit confusing. i've searched around, but most of what i've read came from the 3rd gen forum. so i'm wondering what settings you guys are using so i can use it as a guide when i install and tune it. i'm looking to run 8 and 10 psi, so any advice would be appreciated.

 

anyone?

 

well it all depends on what else you have for mods. me for example, intake and full exhaust (no cats). it was a bit confusing for me also until I started playing around with it. I have mine set at 18% low boost and 25% high boost. low boost runs no higher then 10psi. high boost runs around 12psi. my gain is set at 38% for both. and the gian % is set at 3. now remeber that there's a gain and gain %. gain % is your start boost. I would start out around 15% for boost increase, you shouldn't run into any problems but do watch your boost, your car could act different then mine. if you have other questions feel free to ask. for the best results you should put in on the dyno so you can watch your air/fuel. thast my next step.

 

as for mods i have intake with home made tid, full exhaust with no cats, rewired walbro, and a few other little things. i guess it would also depend how large your wastegate is ported. thanks for the input, i'll use your settings to try and find mine.
