Hey guys I just installed a CAI on my 10 Civic ex. No idle issues or anything just when I press on the throttle it sputters then after it drives like nothing. MAF is in correctly and no leaks. Anyone know what’s causing this?

You don't absolutely need a tune but a tune will allow you to get all the benefits from the Cai the hp and tq that is. You need to reset the ecu just take neg term off the battery for 5 to 10 mins and then put it back on. Although if you plan on doing any other upgrades I'd do them before you get the tune so you don't have to get another tune as they are expensive. You could have a vucum leak that's prolly your issue because it should be doing that after installing an intake as the only issue you should have is maybe running a tad lean as its a bigger intake but resetting the ecu will help with that as it'll reset the fuel trims and relearn everything. A tune is best but not needed.
