The non-intercooled L series has a mechanical injection pump so cannot be chipped, remapped or have a tuning box fitted. 

But don't despair, you won't believe the performance improvements which can be made RIGHT FROM BELOW 1500rpm. 

It costs absolutely nothing but a few minutes of your time.

Some tuning firms call step 1 "optimisation" and charge upwards of £150. They would justify this by citing the dramatic improvements in performance, even from below 1500rpm.

Now you can read how to do it yourself at no extra cost. The other mods are optional and can give even more performance.

Once you've made payment, the guide is emailed to you in Word format within 12hrs. (usually within an hour or two)
