Stage 1,2,3? What does it all mean?
In most tuning circles you will often hear talk of tuning stages and see tuning companies offering a â??stage 6 upgrade for £ra*e.99â?. A lot of this is often just marketing rubbish and can be largely irrelevant. One companyâ??s stage 3 can be equivalent to anotherâ??s stage 5.
In terms of 306 Diesel tuning we talk about 3 stages and they have a commonly accepted, but often unwritten meaning.
These are just the basic meanings as in a future guide we will go in depth on exactly what each mod does and why you need it.
HDi
Stage 1 is usually just a generic remap but is often associated with exhaust and air filter mods too. This will see 115-130bhp.
Stage 2 is a FMIC (front mounted intercooler), the turbo wound up a little and a stronger remap. This will usually see 150-160bhp. This power level is too much for a standard clutch (even a brand new one) and so you will need an upgrade as described in other guides.
Stage 3 is a combination of a bigger fuel pump (usually from a BMW 330d or similar), a bigger turbo, modified injectors and an 1800bar fuel pressure sensor. These mods will need custom re-mapping to get the most out of them or in some cases even for the car to run atall. These modifications could potentially see massive horse power but the limit of the engine internals is said to be around 230bhp and in reality there is very few cars running over 200bhp.
XUD
Stage 1 is usually just turning up the fuel pump but is often associated with exhaust and air filter mods too. This will see 100-130bhp.
Stage 2 is a FMIC (front mounted intercooler) and more tweaking of the boost and fuelling. It can also involve internal modifications to the fuel pump such as a gov mod and grinding the LDA pin. This will see 120-150bhp.
Stage 3 is a bigger fuel pump (usually off a larger car or van) and a bigger turbo. This can see over 200bhp but 200bhp is reckoned to be approaching the limit of what the standard engine internals can take.
Obviously there are some non conformists amongst us whos cars clearly donâ??t fit into one of the categories like 1.9TDs running big turbos and fuel pumps without a FMIC and HDi owners who have fitted a FMIC without so much as a hint of a remap.
