i tred searching and i couldnt find anything so my question is, if i wanted to get a chipped p28 with a basemap for my setup, i/h/e, would it be good to run it better than my stock p72? would i see/feel gains ( im not talking huge gains but just better than the stock p72)? or would i be better of just running my stock p72 and getting a tune later on? i also want to know how basemaps work and such.
