Ok I am gonna do this swap with VT stage 1 cams. Do you need a tune after you do this swap? IF so what kind of is the best? I cant do a dyno tune cause there isnt one around for many hours. SO if you guys can help me it will be appreciated.thanks

with the cams you'll need a dyno tune. with just pi heads and cams, you'd be okay without one, but it would help.

basically, your car wont run properly and you wont make as much power as you could with a tune. untuned a/f ratios and ignition timing does more harm then good.

I did the swap with some comp cams, and it ran fine bcisme says, then cams went in and it wont idle properly, so im sure a tune will correct that for me and Im also prob not making as much hp as i should be cuz i dont have a tune either
