Hello,

A Customer wants a remap on his 7.

All he has done is removed the pre-cat :yawn:

What is a safe boost level?

Many thanks

The Ralliart ones use 1.3bar afaik but i reckon 1.45bar is perfectly safe (assuming he has an uprated fuel pump!)

thanks for the quick reply.

I'm just wondering if thats ok with the standard exhaust.

I think the standard GSR exhaust on a VII is 2.25" all the way through (sure someone will correct me if im wrong) You would be better off running 3" all the way through :thumbup:

Just had a quick search through the forum and looks like a standard 7 will peak at around 1.2/1.25bar midrange and should hold 1.0bar at 7k.

Hope that helps, have a quick search if your unsure - tons of information.

I have a 3" turbo back exhaust with sports cat. Running 1.6 mid to about 6000 tapering to 1.3 at 7000. Stock actuator ECU controlled boost with GM 3 port BCS.
