Hi guys. I have 997.2 turbo giac tune and 991.1turbo s cab giac tune. On 997 big difference. Had it 3 days on track and only once had “limp” mode where turbos seemed ro not come in strong. Had to cool down a bit then it was fine. My problem is with 991.1 tune. It didnt feel as strong and the giac agent in south africa said i can only load 1 map(pump i did). I cannot revert back to factory load as there is now space on eeprom according to him. I dont feel this is right. Any experts on giac on this forums? Also need to know my upgrade path to stage 1 and 2. Does this entail diffirent intercoolers ,decat and specific exhaust? What power increase on each step?
