vw 1.8t
looking to increase boost without dishing out $575.00 to get computer flashed. increasing boost manually doesnt work because the computer sees the high boost and puts you in limp mode (5lbs). ive read a few places about tricking map sensor with resistors but again computer catches on. if anyone knows anything about this it would be a big help.

anyone know what the 1.8t will run safely at? 10psi with no ecu mods done.

anyone know how to get the ecu out of limp mode if/when we ---- it up?

Re:vw 1.8t
the turbo is really too small, i tried putting it a 10 but it wouldnt, it just would only peak at 8 after that, so max we would get was 9. o by the way, if you pull the bov outa the intake and plug up the intake it makes a nice sound, but sometimes the cel comes on, and you have to reset the ecu or re-start the car otherwise it will only run 5 lbs. get a boost gauge and its all good. it moves pretty good, we got it going down the freeway a 135 no prob.

Re:vw 1.8t
you would have to chip your ecu to gain more power but its worth it. Vw owners claimed pretty good #'s to addtional horsepower to the wheels. All from just one chip too. As far as increasing your boost you might just want to upgrade to a bigger turbo
