What mm do you all recommend i bore out ny cylinder heads?

Boring out cylinders isn't bolt on performance.

Yes i know thanks...my question on that bore tho?

You can't bore out a computer controlled fuel injected engine without re-tuning it. How are you going to custom tune your PCM? And you can't just send your PCM out for a canned tune. It must be done in vehicle. Otherwise, you are wasting time and money.

Once again thanks...i think i know enough about all that if i want to do a bore dont you think?..
Anyone else any suggestions?

If you know enough about all that, then why are you here asking questions then? Seems you already know everything.
