I'm going to finish my PI swap soon and I was wondering if I need a tune? "Need" being a key word here. I'm piss broke as it is. :'(

I would do it. Your Air fuel will be off. If you plan on doing more mods in the near future hold off. A tune is like giving your car a fresh start and kinda like keeping it up to date kinda thing. I know those are wierd anaolgies (spelling) but you'll squeeze a few extra ponies out of it also. :thumb:

If you dont have the mony then you dont. It may run a little ruff at first but eventually the computer will adjust to the change. It will probubly detect the more airflow and run rich. If you hear a ping though get it done right away. Detonation will kill it.

depends on if you have a chip and how many places that tune. Around where i use to live they charged like 1 g but they were only place in like 200 miles that tuned. Go figure. :rant:

you don't need a tune until you add aftermarket cams, i drove around for 2 years with no tune on my PI swap with all the bolt ons you could think of. I didn't even get a tune after i swapped to VT heads and Comp 262ah's but i barely drove it that often and it would stall at the red light.

Now i would definately get one as soon as you could afford it to maximize the hp and a/f ratio.
