Over the past few days, whenever i have boosted it properly:lol: , i have noticed the car sort of "jumps", feels like it slows down and speeds up, noticed it only happens in damp weather, coincidence? Well i found out that its not actually my engine or anything like that, just my bloody tyres losing grip!! my tyres are in good nick, but they arent performance ones, so i dont blame them for wimping out, guess i have to keep the full on acceleration for dry days:-D
