hi
on my three door im running a t34, rs500 cooler,gpa fuel pump, -34 actuator ,greens, im not sure what the chip is...running 28psi..365bhp.........
compared to my stage two sapphire it is a lot more aggresive ..when the boost comes on it fookin comes on(seems to be all at once) you cant floor it in the wet .and it pulls like a train to the limiter....but it all depends on the chip they are all mapped different and have different characaristics..
but to sum it up you will certainly notice the difference...
