I hope this hasn't been covered to much before, but i just bought my very first mps and im ready to begin a few modifications, i called turboxs and spoke to the very helpful gentleman about a few things with the mps but was brought to my attention with the gen 2 you cannot make any changes without a following tune or the ecu resets everything to minimum.
So im just interested in what i can do without having to put the car in for a tune?
