2.0 abf on kjet help please

[t-dub1902]

Hi guys
Ive got a mk2 with the set up in title

It says on the mfa its only doing 10mpg
It runs ok but not 100%

Now i was going to rip out and 20vt it but ive read that the abf on k jet can be a good setup

What are the options to get it running good at what costs?
Im thinking the wiring is poor and would need redoing maybe ( at what cost?)

Any help would be great
Cheers

MFA dosent mean much tbh  it could have a vac line issue.

the problem is likely with the K jet itself people rarely ever calibrate it oter than pissing about with the co screw

1st off you need to check the injector spray pattern, then match injector flow rates,  then you can check system and controll pressures,   then check the warm up regulator isn't working, strip clean and un sieze it, then reset system and control pressures.

then set the co.

if you really want it to go some, a  hybrid  volvo or saab / vw  metering head helps a lot as can end up right at the top of the adjustment of the vw metering head  like 6.2 bar system pressure and naff all control pressure.
