[Joel93]

My girlfrend has just bought a 2004 polo 1.9 tdi 100bhp sport, my 2 options are tunning box or remap to achieve 130bhp and more torque any advice on which to go for ???
Any good remapping companies near me Wrexham , Chester area ?
Thanks

Well the 100 was close to us and I knew they could be tuned, well it's just a golf engine so reliability should be good,
Thanks
