ok so my car....
a4 b5 quattro sport. with a ajl engine
it runs good, no problems what so ever, apart from a small fluctuation at idle.
it does run ok but mpg is out the window, sometimes £30 lasting just 100 odd miles. and theres no real loos of power, just lack of it. pulling away is good but after that its slow! i mean compared to a friends golf 150hp 1.8t any way!
so im looking about the engine as i was cleaning it and
lookied and my fpr and its 4bar!, the turbo is a k03-029 and i believe the sport quattro should have a ko3s
the car seems to have no were near 180bhp its slower or feels slower then my mk3 golf gti!
the car runs 18psi, no boost spikes and levels to 10 ish psi after 5k as expected but looking at logs and expected boost, its almost like the car is wanting for more
almost like its mapped for a bigger turbo
how can i tell if its been chipped, and if its been mapped for a bigger turbo and someones slapped any old k03 on there to keep the big turbo,
im right by saying even the sport shouldnt have a 4bar reg, im also sure the bumpers been trimmed for a fmic, again not there.
whats the best way to figure this out and what can i look at int he enigne bay to find out? also i think i might have 2.0t coils on aswell?
is it even posible for a k03 to run on a bigger turbo map? ie a k03 hybrid or even a k04?
