Other Stage 1 maps out there do have more power but depends what you are looking for. I would definitely consider a Litchfield’s tune as what they do for GTR’s is excellent and sure they will produce some great packages for the Mk3 RS.
Good at what they do but charge the earth, and the customer service is “questionable” as i found when i had my GTR….Unless your forking out the kings ransom on engine & box builds that is 🙁
