Yeah it did feel like it had an extra 50 horses it went like sh*t of a shovel! I spent alot of money on the suspension after that to try and put the power down. As for the fuel my dad had exactly the same car but not re-mapped and his did about 50mpg but he drove it steady and mine i used to drive very hard and never got less than about 37mpg. But mine is a diesel and yours a petrol so not saying its going to be exactly the same obv.
But trust me jabbasport know what there doing and are really keen, last time i went up there they had a A3 2.0T Quattro running 400bhp! and i went out in there Skoda fabia tdi that was running over 200bhp, you won't go wrong having anything done there mate.:icon_thumright:
