    G8 Tune

    I purchased a G8 last week and I knew something about the car wasn't stock because it was much faster than the other car I test drove so I pulled the tune and compared it to a stock one. The cars definitely been tuned, but I'm not sure if whomever tuned it did it correctly. Would anyone be able to look over both the engine and trans tuning to see if its a good/safe tune. Also is it tuned for 87 or 93? Thanks

    Idle speed was raised slightly. DOD Disabled. Power Downshift Tq reduction disabled. All the transmission changes are to accommodate the 3.25 rear gears. That's why it feels faster then the stock 2.92 gear G8's. No changes to timing or PE tables. Safe to run on 87 if you want.
