Mine runs well enough with the cone on a higher cam, but I do intend to get a box at some point. See how it goes with the cone....

May be worth printing off the guide and taking it to the garage doing the work, as the procedure is specific to this model (timing set at 2500rpm and sensors disconnected etc), and so it would be easy to have it done incorrectly by a mechanic that isnt familiar with the digifant system.

i think i got it sorted now i changed the blue temp sender today got one from gfs as only payed £5 from work :) so cheaper to change them every 6 months than to buy a Vw one lol. once senser changed i tuned the screw on air meter head right down then up quater of a turn, then ajusted idle, car seams to idle normal now and fuel gone up to 36ish mpg on a small run but in 5th not been on long run yet but all looks promising, still going garage sat morning to get the co meter on car check not burning to much fuel but looks promising.

Stress over lol

wouldnt stress too much, when i had mine first it read 18-23mpg, just ignored it as i new they could lie anyway, later i found the vac pipe in the bay wasnt in properly so pushed it back in and voila max of about 35mpg! not that it ever bothered me as i loved the car!
