hi im thinking about tuning my 1994 wrx ,which has got the sti engine but wrx wiring loom, is there anything that i should avoid and also il thinking of taking it to the nurburg ring which is about 800 mile round trip is there anything that i should check befor going cheers

 

Are you running the Sti ecu too? This would give you some cheap extra power.
