I recently took the plunge and decided to go stage 3 TTE700 on my Rs3 fl and overall I am pleased with the results that the car achieved on low boost settings for safety.My mods include Bcs de cat, forge intercooler, full eventuri stage3, uprated spark plugs. Plus I have a few more mods to go which include full exhaust, intercooler intake pipes do there should be gains to be had there. Is there any other part people have changed on there stage 3 set ups.
