I had mine done at JBS Auto Designs in Chesterfield, and what a difference it has made to my car. It was a 1.8T sport with 163 bhp. Now its got just over 200 bhp. Always puts a smile on my face now when I drive it. May get the stage 2 done soon.
To get them sort of figures, you need to get a stage 2 remap. That includes, full exhaust with sports cat, air filter, forge diverter valve etc. Your looking at around £1000 for that
I remapped mine my self using a tuning file from Celtic, i have a K04 Turbo, FMIC, Uprated Cam's and Sports Cat/Exhaust. Its about 240bhp i think atm, need to get it on Rolling Road.
paid 390 with a new dump valve fitted ,map was written for car not generic like some others and done at my home .Was a 163 sport now 213 bhp all went ok only took it for a few miles after but car now fell faster and smoother,car fells like a proper car now
