Well as some of u know I recently went to rtech to remap my car custom stage 2 whilst there nick advised me to replace my coolant temp sensor and get a new maf as mine was still original one with the car, 12 years old! So off I went today and replaced the maf got a new one from my Audi dealer and wow nick ur the daddy! The car felt so much better and responded so great had me smiling all day! Im so grateful to met nick and got great advise was well worth it! Also while st Audi asked them to sort out the corrosion on my roof lines so will see what happens there but overall a happy bunny and can't wait to get to rtech on the 22nd to up my boost to 21-22psi I'm only running 15 now so will be another great day I hope!
