Think my k03 may be on the way out the window. Been working on the car anyways and wanted to do some upgrades regardless.... I have a appointment to get my car a 93 octane tune threw APR TUESDAY... If I replace my k03 with a k04 after i get my tune is it going to be pointless will i need to get another tune?

Next question

Ebay K04 OEM Upgrade? Guessing NOT OEM. Is it ****?

Third

Do i need injectors? 225? Again will i need to get another TUNE?

Or sould i just postpone APR 93 octane tune. Put the K04 and injectors than tune.

 

yes you need to get a reflash for k04 and injectors are required for k04 tune.

by the time you pay for what ever flash you are getting now and buying the k04 and injectors and then getting another flash/tune, you might as well just buy aprs k04 kit because you will be spending abou the same and the tune is included with their kit.
