I'm in the process of finally tuning my car, nothing big right now, but I was strongly considering buying the stage 1+ tune from Motoza Performance. Buying a high flow cat or test pipe, don't know which right now, hoping to get more info from someone here with more knowledge on them. Also getting a k&n air filter, and a 710n dv. Would also like to know what kind of injectors I should get. Any info on the matter would be appreciated. Or if anyone here has gotten the tune and has any positive or negative feed back.

 

I was thinking about some tt225 injectors but they're $400 bucks so I was considering some bosch 380cc injectors that are apparently for the 2.0l. Here's a link to them, Audi B6 A4 Quattro 1.8T > Engine > Fuel > Injectors > ES#2594193 Bosch 380CC Fuel Injectors - Set Of 4 - BOS380CC4

 

I would say it depends on what your future plans for the car are. I would imagine that Motoza can send you a tune adjusted for the 6cc flow difference, but there may be a reason why most stage 1+ tunes require the 386cc injectors. Spray pattern comes to mind as a possible reason - all injectors with similar flow rates are NOT created equal.

I'd email Motoza about it. That said, if you plan to go to a bigger turbo further down the road (Frankenturbo or GTRS, for example), it might make sense to ask if they can do a stage 1+ on some 440cc injectors (green giants) instead so that you'd only have to buy injectors once. Basically, I'd say you need to talk to Motoza about exactly what your goals for the car are and they'll be able to advise you on the best course of action.
