I got 1.9's and I did not tune mine at all, just reset your PCM... ie remove the battery connection for awhile and add it back... your PCM will begin relearning.
You will want to do a MAF tune first btw... Fuel>Spark>Boost
the PCM will never re-learn the added amount of air youre pushing with rockers. you need a GOOD tune.
So a VE Tune you recommend?
so you dont have to do a VE Tune?VE tune is optional, but a good idea. Then do a MAF tune and see if you can add some spark. You will probably need to adjust your PE fuelling so that you don't go a little lean now that it's flowing better.
^ yup. Buy a wide band too.
