I have a 2000 w reg mk2 hgt, and while i did not get it for fuel economy (these are thirsty little beast aint they?), today it was reading 21.7 MPG?! I was not even thrasing it, was driving very conservatively (like a granny) and was shocked at this readout, normally bewteen 25 and 28 mog (i normally get 55 - 60 miles out of £10 under normal driving conditions). I want to fit a pipercross viper induction kit and want to know if this will kill the mpg to an al time low? Also i have a powerflow b/box, if i couple this with an induction kit will this cause the engine management computer to come on, as the power will be different? Would the gsr induction kit be a better option?! Also any ways to improve mpg? Only had car since november and shocked by mpg!
