Tim from Tewkesbury with a John Deere 6630 6.8 4V R6 said:
Fitted first to a John Deere 6630. It transformed this tractor from 125hp up to 157hp. So now have two more on my John Deere 7530s and it takes them to well over the 220hp - all for no extra fuel. Great service from Chip Express - answered my questions before purchasing and sent it out very promptly. Thank you. Everyone should get one, or two!

Just to let you know I fitted a CHIP Express to my JD 9770 Combine with excellent results, more power and less fuel (8 to 10 litres/hr) making harvesting a lot easier under difficult conditions. I have had the unit over 12 months now without any problems. The chip is priced very well compared to other brands. Thank you very much!
