Difference between DBW or non-DBW on a B5 A4?

Cable driven throttle (DBC) vs an electronic driven throttle (DBW) where the ECU basically is in charge of everything. Some say that the ECUs on the DBW vehicles can at times have a mind of it's own due to this.

Does the TB change for piping at all?

DBC: 96-99.5
DBW: 00+

The piping for front mounted intercoolers (if that is what you are trying to construct) are all the same. The only difference is you would need to have a flange for the MAP sensor welded onto the cold side piping for the DBW vehicles. Just out of curiosity, you plan on making these fit behind the stock bumper w/no trimming (no trimming of the bumper is what would make it sell)?

With zero trimming.

How does Racetec fit? Good?
Do most people weld a flange in?

If a person wanted to have a front mounted intercooler and owned a DBW, a MAP sensor flange is required. The measurements are needed by the ECU for your car to operate. The DBC vehicles don't have MAP sensors.

Racetec FMICs are the best on the market for people whom want an intercooler with little to no trimming (some don't need to trim at all). But the issue is if people want to run applications grater than maybe a GT2871R, the Racetec intercooler just won't cut it. When ordering the Racetec, you need to say which application you have (DBC or DBW). They already have piping with MAP sensor flanges welded into the cold side piping and would ship that one with the kit if a person was to order. And people whom peice together thier own kit most of the time simply weld in their own flange.

Any idea on what pricing will be, what core you will be using with your kit, will it retain OEM fog lights&grills, and effeciency? Or are you just trying to gather info at this point? And just as a formal warning, it is not permitted to advertise on Audizine without a vendor's account. But I am def interested in the outcome of this project.
