It does exactly what was claimed

andy ,Skoda Fabia VRS 1.9

Visited Tunit in Chorley where I was warmly greeted by Lisa, Dan and Michael. To cut a long story short, I brought my wife's 2006 Skoda Fabia vRS 1.9, which gave 150.1bhp and 269.4 lb/ft torque when placed on the rolling road. After Tunit weaved their magic, the figures rose to 176.2mpg and 318.2 lb/ft torque. Plus, average mpg ony journey there was 62; on the way back it averaged 68!Impressed? You bet! Driving impressions? Stunning! Would I recommend you visit them? Unequivocally 'yes'! I will be submitting a full review shortly, suffice to say I am suitably impressed with Tunit! But don't just take my word for it, go and visit them yourselves; you WON'T be disappointed!
