should you back that up with larger injectors?
I could only find one post on this while searching and it lead me to believe that you do.
thanks

Parts, tranny and labor etc.... If you are replacing the MAF to 225 do the injectors from the 225 as well I forget what cc they are sorry.

I have a TT 225 housing & one of the BAMM housing the TT guys use (11% bigger than the TT 225 one).
The TT guys run the BAMM with a 4 bar FPR (instead ofthe stock 5 bar).
The 225 one won't fit in our airbox w/o making the whole bigger. The thickness of the BAMM walls is thinner, so it might.

mine blew.
Low Mileage 2.8 Tranny was 1050 from a yard.
bolted right up.
Things to look for.
Consistant chips out of first gear caused by the housing (makes 1st clack, most embarasing thing I have ever experienced about a car)
Its a casting flaw.
cheers

that was my only real question I guess.
Is it safe to run it (if my maf goes) until I get a larger turbo setup.

do you mean the maf sensor or the housing?
if you mean the sensor, no because you have to use the sensor for an awm motor. i've seen posts of people in the passat forums trying cheaper sensors with no success.
if you mean housing, still no because the ecu will be seeing less air than is actually entering the car = lean = bad.
the only reason the TTers can do it is because they are making their MAF housing larger (so the ecu is seeing less air than is actually entering the car), so in adjustment they up the fuel pressure (iirc their stock fpr is 3bar) to 4bar which is what our stock pressure is.
now if you want to put on a TT225 MAF housing, and change to a 5-bar fpr. i have no idea, you're on your own man. need to do some calculations.
