Performance Modifications for the NG900 / Old 9-3
What up?
I've got a 99 9-3 HOT and am on the verge of a Stage 4 car, here's what I have:
TD04
GS Intake
Saabsport exhaust
Upgraded intercooler
Forge BOV
Here's what I think need:
Tuned ECU
3" DP
3.5 FPR ???
My questions are;
1. Do I need the 3.5 FPR and at what point will I need to upgrade...
