I have a 07 saturn aura xr and I'm looking into having a dyno tune done
Using hp tuners. I'm only having it tuned for 87 octane and was wondering if it's worth having the tune done. I would be having the ECM and Tcm tuned. Has anyone done any 87 tunes that would give me their opinion. The only mods I have on the car is cold air intake. I'm having a 87 tune done because I have a company gas card and that's the only gas that's payed for.
