Hey guys,



Finally got my TII vert running 100% well.



After I removed the linkage for the double throttle butterfly and wire them open, the car has the power it should of had, strong.



I've been using haltech and wolf 3d for the past 15 years on my S4 TII and have forgotten little things about the stock system.



I would of done RTek but their 2.0 version is not out yet for the S5 Turbo.



Right now my S5 TII vert is running

S5 stock ecu 370 with FCC

FD fuel pump,

RB turboback exchaust

Still running the stock air box.



Now i'm showing leaning out on 3rd gear pulls because of the added air coming in now.



Way back in the days i used to use a SAFC and regret selling it when I went Haltech.



Are there any new options out there. I'm surprised the currect and old SAFC still cost over $300.



My car is to remain fairly stock with a 3" Cat being placed in soon after I tune it. Everything else will remain stock.



I don't need any more power, i feel like i'm going to die because it has no top. I want to make it reliable for many years.



Please let me know of what's out.

What is lean? If its not too lean maybe you could just add a water injection kit and call it a day...

Lean as 13.0 AFR as it approaches 5.5k rpm



Water injection is too extreme for my S5 as is going to be a nice weekend cruiser. On the other hand the S4 track car might benefit from it.



I want to keep it stock as possible with slight mods to keep it reliable.



Gotta hook up a boost sensor and see how much boost is making, feels like 10 psi.



I want to make this care civilized, lol.

Put the cat in, boost should come down and so should the afrs..

more fuel yahoo

my favorite set up for street cars is this:
