205 Gti 2.0 Turbo

[gledhill 0]

hi this is a new engine and new conversion.

the car starts and runs but seems like it has not got its grunt (i built one a couple of years ago 260bhp) and i know how they should go.

 

so far ive changed

lambda probe(and checked power to it)

throttle body

injectors

fuel press reg

water temp sensor

 

it doesnt just run a little rich, the plugs get sooty within 5-10 mins

i havent plugged ecu in as my 2 reader wont access it. i have ecu pro (for the laptop) and an autel vag. which ones work with the car?

 

any advice would be great
