Last week I ordered an AP from Stratified with a flash tune and optional datalog refinement. My only engine mods are an Injen intake and exhaust. I'm running the 91 octane flash tune and everything seems to be great - very rarely do I get negative corrections, and sometimes see up to +3. So my question is should I use my datalog refinement now or wait until I get an intercooler upgrade? Has anyone seen performance increases after a refinement when having very few mods like my car? I am running 92 octane fuel on a 91 map so I do think it could be taken a little farther. Thanks.
