Car very jerky under acceleration - runs full boost, maf fine - no engine fault codes - only thing is the advanced multiplier value is 14 and suppose to be 16 I am told, is going on the rollers tomorrow for full check - anyone any ideas?

car is 1999 turbo uk.

cheers ade

 

You sure the maf is 100%?
Mine passed all the tests mentioned on here, took it to dealers and it was fooked. £80 and sorted though.
