Ppl apply twin turbo's to these and make silly horsepower ! Like 12-1500...
Tractor chips

RS4 4.2 V8 is naturally aspirated so it's expensive to start strapping superchargers to them to get decent power gains. I had my B7 RS4 custom remapped by MRC Tuning at Banbury & they could only get another 13 hp or so out of it but another 25 Nm of torque. It was a B7 model so prone to coking up the valves thanks to badly designed swirl flaps & FSI direct injection (no fuel washing the valves off). It went in at 380 hp & came out at 427 hp with a new inlet manifold, cleaned valves & a sports exhaust to help it "breathe" more easily. My neighbour though he could hear a trawler chugging past his door every time I went out in it
Remapping a car that only relies on peak power occasionally is one thing. A cheap chip on a tractor giving full power all the time is another.

I'd like one but think that V8 might be hard on the driving licence.
Kinda resigned to finding a nice R32 Golf. Been looking but colour, spec, and price to suit me is hard to find.
Fed up of driving pickups or crappy A4 diesel multi auto.

The trouble with the R32 is it sounds that nice your inclined to use the loud pedal way to much! I had a mk5 it use to average 8mpg and destroyed the tyres in under 10k miles
. Got a 4.6 v8 x5 now (family car) can’t beat the sound of a v8 though. Anything less than 6 cylindes isn’t really an engine is it

Apart from the normal damage to the injection system, what other engine damage are people seeing that can be associated with chipping?

Unless the rail pressure is ramped up, the injection system is unlikely to take any harm. The challenge when tweaking a common rail engines fueling is not so much the adding of extra fuel. It is when that extra fuel load is injected during the cycle that makes such a difference. Get that wrong you can have poor fuel consumption and/or combustion temperatures rise, and high combustion temps is how you have a severely shortened enging life.

Yes, and no.
In our modern times of modular standardisation the same engine can be fitted across a huge range of machines and with a huge range of power outputs.
Take the FPT 6.7 for example as found in the large majority of 6cyl Case and New Holland models.
It is available in anything from just over 130 hp to over 300hp, and in other non farming fitments can be had upto 500hp from the manufacturer. These are all broadly similar with very few mechanical differences ( different turbo and intercooler) across such a broad hp range
So it's the same engine...but different ? Don't forget torque either.

Thanks for that. Just looking at buying a JD 6220 se that had been chipped at one time but it has had a new injection pump and injectors since.
Remap it if possible, you wont regret it. I've had JD 6230P remaped to 125 HP and closed EGR and after that stock JD 6430P and 6230P was better to drive, especially in E and F groups. Engine temp went down to 83-85 degrees and it needed 1-2 liter less for the same job. For easy jobs you drive it in low revs so it eats less fuel.
I have done it at dealer of Allcartuning aka. ACT from Austria.

I know some places give you the option of remapping and replacing, if you send them an email I'm sure they'll help. If not I can send the link to the plug and play kit I own? Think I bought it off https://www.unichipeurope.com/group/Shop

Remember a rep telling my dad when he couldnt decide between a 100hp turbo 4 cylinder and the same brand 100hp straight 6 cyl " that it was like trying to shove a 6" shite up a 4" pipe, never going to end well"
