[QUOTE="DD2000GT, post: 15474772, member: 4538"] An update on my never ending saga on this car. I took it back to the dealer and requested the car to be re-flashed with the stock tune. Their head service guy asked why, and I told him I wanted to put a tune on it and need to ensure the base is the stock tune. He said to just let him look at it and see why it bucks in 1st gear and has the RPM hang when you lift off the gas. Had it for two days and called me and said he discovered this car has a FRPP 90mm throttle body on it as well (this is a new to me used car and I have no idea what was modded on it, I am discovering as I go). I "think" if it had a tune on it when I got it, and they reverted back to stock tune this would cause this symptom(?) However, they still will not say they re-flashed to stock, but the "tech" said he was SURE the stock tune was on it... A few questions - without knowing "exactly" what tune is on my car, can I just get a tuner, save the current tune, then reflash with a tune for my mods? Also, if they put a 90mm throttle body, they "might" have swapped out the injectors as well. How can I tell what injectors are on there now so I can add this to the tune mod list? TIA [/QUOTE]
