That's cool. How much does ESS charge for this?
Also, is there a drastic decrease in power if I runthe 2.5 injectors and the 2.5 maf?
Anyone did dynos?
And bow do I remove/install my ecu?

Sorry of it's like I'm asking so many questions. I just want to learn everything and be fully prepared before I start this.
