Unless I'm missing something a t5 needs a bit more than a chip and exhaust to make over 300
Rica 305 chip doesn't mean 305bhp, think it's just the part number
They love it though, the later 2.5 block tends to split it's liners even under stock power. Older 2.3 with the right rod combo are the deal.
Volvo v70 t5 sub 100k chipped and exhaust to 320bhp. Needs set of tyres and maybe rims...what would it be worth?
