my old spec was similar to the 1 i have now,it was a second hand ahmed 200 bhp chip (i was told),it made 164bhp atw on avas rollers.wont use them again btw.i felt that that chip made the power up the revs.the turbo was a stage 2 t3 from the same guy i got the chip from,i just felt it was rather laggy.what price do you pay for ahmed chips?i emailed grove garage last night but i still havent had a reply.
also anybody shed any light on whether the fuel ecu needs modified?ta,lee
