Tuned But Not Going Well Now!

[Turbo Dave]

Got my car tuned a week or so ago and have only driven around town until today, just arrived in Sydney and it running like crap! stayed off boost as much as possible on the way up but still averaged 13.9Lper 100 which I reckon is a bit steep!

Light load driving is good but but it missfires and pumps soot out the back under high load.

Can it go out of tune? Or has my highway tune fouled the plugs?

Checked for air leak after the AFM?

Might help to include some info on your car dood lol, how are we supposed to help if we don't know sh!t about the car???

What ECU are you using?

look for a boost leak, id say a vac line is off. If in doubt take it back to your tuner. Cars dont go out of tune, unless something changes.

Cheers I will have a look tomorrow and if I have no luck I will contact my tuner and get it sorted.
