Does anyone here have any experience tuning their 4.6? I know I can bump the timing and take advantage of higher octane fuel, but I don't have any direct experience with the 4.6. I would probably just add a staight 4-5* across the board, but maybe someone can describe a better strategy?
Also, AF ratios are a bit funny with the stock tune... in the mid range, it is pretty lean, around 13.5:1, and fattens up to 12.2:1 by redline. I'm thinking I'll make it around 12.9: in the mid range, and lean out to 13.2:1 by redline. Any suggestions on that?
My modifications are very light. I have an offroad H pipe, PI cams and drop in K&N, but I think a tune will make the car a bit more fun and snappy.
I ask because I recently bought a Tweecer, and it should work on both my 2.3 LX and the 97 GT.
