I already have an Injen CAI and Injen Catback now. In February Injen is releasing their downpipe. Once I get that installed I qualify for a level 2 ECU flash from COBB.
I spoke to Craig @ COBB already and asked him about the intake. He said they already have maps for a Injen Turboback and Injen intake. He said if the intake was causing a lean condition from the mass air flow the maps would compensate for them.
I'm going with the handheld flasher through COBB so I don't have to send my ECU in to them.
So please stop worrying about my lean condition
well crap, i shoulda been quicker with my writing... yeah, this says the same thing as the couple posts up.. but i swear they weren't here when i started writing!
move along, nothing to see here...
Thing is, you probably don't have much of a "lean condition" now, but if you were to try to use regular reflashes from cobb or vishnu or whatever you would. Since their maps do the same thing through proper tuning instead of through improper maf changes, you basically end up applying double the "lean condition" effect to the car.
So what about cobb's custom map for your intake? Well, I'd like to know if their injen intake stg2 map makes any more power than their standard stg2 map. I'd be willing to bet my intake snorkel that it doesn't, mainly because they will be tuning around the lean areas of the map that exist, or perhaps even putting back in some fuel to compensate. THIS is where the waste of money comes in.
There is absolutely no question that an intake with a larger maf tube will cause your car to run leaner... it's straight physics. If your end goal is cheesy bolt on mods like a CAI and catback, then it will be fine. If your goal is to go even stage 1 with your car, it's a waste of money. Hell, if you really wanted to, you could get the same effect that your injen CAI gives you by buying one of these cheap-ass resistors off of ebay:
It just modifies your maf signal to do the same thing, instead of using a larger pipe.
