hi, having had fronteras of every type over the last 15 years (v6 auto my favorite) i now have one just for a second car as i just love them!,,,i run a santa fe 2.2 diesel daily and covered 230k untroubled smooth miles regularly towing 2.5tons!!, its a fantastic car but a weekends i run my frontera, the only problem it feels so slow after the santa fe, is there any kit/procedure that anyone has succesfully got more power out of the 2.2. petrol unit without blowing it up?
