i have a 3 dr cossie and bought a collins stage 3 chip , all im wondering is what boost i can run it up to . my spec is
t34 stg 2 hybrid .48 housing -31 actuator
grp a coil , k&n , fuel pump , headgasket .
803 injectors
L8 ecu
4x4 plenum,throttle body and inlet manifold
motorsport ign leads
champion 57 plugs
pro alloy rs500 intercooler
running 18psi peak ,16 psi hold
any info will be great . cheeRS

 

For the cost I would get it down to a good ROLLING ROAD, so that a full load fuelling check/adjust can be made SAFELY without risk of engine damage!!
My check cost me £30, so cheap piece of mind.

As Tabetha says, you'll need a fuelling check as you cannot be sure of the map.

I had an almost exact same setup as you with only a standard 4x4 IC, and using an MSD chip, and was peaking 26psi and holding 24psi, so you should have plenty more to come............

I used to have a very similar setup which I ran with about 24psi peak and hold!

Mine was using a Bayjhoo Stage 3 chip.
