I have a 1997 r33 Nissan Skylines and if any1 could give me instructions on what setting needs to be at what to obtain 12 psi i would greatly appreciate it. thanks!

Hey dude,

I have one. Each setting affects the settings of the others. It's a pain in the arse to tune on the road.

The settings would vary from car to car too, depending on your turbo, air filter, and exhaust.

Here's my setting for 11psi

1997 r33 gtst, full 3" exhaust, hi flow cat, pod air filter, and fmic.

HI

Boost -> 50%

Gain -> 15%

Set Gain -> 53

Warn -> 14

Peak -> ON

Try increasing the "Boost" and Set gain.

The "boost" will increase the boost pressure and set gain effects the smoothness, the closer to the boost level, the faster it spools and more chance of a spike, especially if setting over 50%
