hey was wondering if anybody could help out. Got a 99ws6 A4, only mods are 3.73 gear and borla catback. I was considering putting on a NOS-05177 kit. Is there any other suggestions to stuff that I might need in order to keep everything in one piece. Any help or similar situations would be great Thanks

 

I would pick up a NOS purge kit, a window switch (I got a Harlan), and a bottle heater. The kit should have the wide open throttle switch and the FPSS switch. I chose the NOS heater and replaced their 85* thermostats with 95* stats. I am always right about 1050 psi.
