I do 15k miles a year and I am usually just cruising to and from work. However on the odd occasion when I fancy a little fun, I am somewhat bored of the standard power. I know these map really well with impressive results, I am just a little cautious with the mileage.
Anyone with any experience on remapping on similar mileage?  |
It should be fine, but if possible you really need to check your rad bearings.
As the temperature gets higher in the engine block, diesels can cool themselves by injecting more diesel fuel in the engine, so there is an excess of heat.
A bigger intercooler is really needed if you want more power and don’t want to destroy your engine.
Attached are some pictures what happens if you don’t check your rod bearings before you tune your engine.
