Fitted a Gstar chip to my digi 2weeks ago and was surprised at the difference in torque,revved better aswell but more impressed with normal drivin improvements!didnt notice any better consumption but get up2speed with so much less effort.Tesh is freakishly helpfull aswell,takes a genuine interest in how u have got on with fitting the chip.Payed a bit more but was happy with my purchase.Would also like2add that rubb john&slick have given the best advice i have come across-top guys!!!Also drove a 911 GT3 today and have to say those modified BEETLES are awsome ha.
