It all depends on what you have done. If you need a tune because you are putting more air or fuel into your engine then you will need a chipped ECU. If you have a turbo and use a stock ECU without a tune, you are going to run lean and blow up your motor.

Do not run a stock P28 or P72 on your H22, they must be chipped for your setup. For now, stick w/ your P13, then move up to a chipped ECU.

thats the thing finding a p13 is hard i dnt have one

[Granite CB7]

^Oh, gotcha, I understand the frustration! Well, it's either finding a P13, finding a stock P28/P72 or P06 + similar; having it chipped + tuned, or buying an already chipped 1, but you'll still need a tune. The tune is recommended, but you could run on a basemap safely w/ easy driving.

you should run a chipped P72 if a p13 isn't available. You can run a chipped p28 or p06 if you're going to be running an aftermarket intake manifold. I've seen nice power gains from tuning even a really mild h22 vs. stock ecu.
