a4 b5 2001 AWM cheap interooler
Hi guys im planing to do the cheap-*** intercooler diy but as you know my stock intercooler has the pressure sensor or map attached to it. Is there a flange or a relocation kit for it? I know its not good to remove it. And I aint paying 900 bucks only for a sensor flange intercooler

You'll likely have some unpleasant pressure drop if using a fmic w/k03. The stock smic is fine. The ecu checks manifold pressure through the map on DBW engines, and if there are inconsistencies with that, so will there be with your fuel and timing- possibly (almost certainly) causing a lack of performance. A loss of a few lbs of boost can be significant, especially if you're not chipped. It'll also take longer for manifold pressure to build if you are increasing the volume of space that the boost has to travel through. Remeber that the ecu compares what the N75 says and what the map sees. If there is a big enough gap (pressure drop) between the two then you'll be dealing with boost faults, CEL, limp mode, etc. If I were you I'd save that money for a chip if you don't have one, suspension, maintenance, etc.

hey teeter sorry about these ******* noob quest. but do you refer to proper tune as a/f and boost? or only boost. and would the stock smic work well with a gt28?

a/f and boost, as say if you go with a gtrs, you obviously cannot run on a stock tune. you would have to get a proper big turbo tune from unitronics http://www.unitronic-chipped.com/ or some other company. the stock smic will work but not well.

Fact is that most good FMIC cores will have less then 1psi of pressure drop even on a K03.
My car was used for R&D/testing for the Evoms dbw B5 FMIC kit way back in 2001. I saw no big pressure drop and even gained power because the ecu wasn't pulling back as much timing even during a 1 gear pull.
So a FMIC is very helpful even with a K03.
The key is to get the correct size FMIC for the size turbo being used, they are rated by HP. Problem is too many people go and buy cores that are good for 600-700hp when they aren't even making 400hp.
