If you sell Link for around £450/500 you can go get nistune plus mapped for only a small amount more. Link will cost £500 minimum just for fitting/mapping but does have extra features such as Boost control, Map sensor, water spray control but if you don't need these functions results may be better on Nistune in terms of smooth everyday setup & save you a lot of money.Nistune works well & has good tuner knowledge & easy future maintenance/adjustment ... Also cheap & easy to buy a used greddy boost controller or similar for use alongside Nistune ...
