i have a 530d 2004 model and looking to have it tuned by a company in the UK called upsolute.com. they claim to increase bhp to 248bhp with a 10% saving on fuel economy for ?305 all inc.

any one heard of this company. has anyone tuned there e60, and finally is there is chance of damage to the engine.

your input would be welcome

 

I have heard good reports on the company. Do a search on the Company's name in the "Parts, Accessories, and Mods" discussion. You mght want to develop a somewhat skeptical attitude on what after marketeers claim, but their claims usually have some foundation in fact.

 

the bottom line is that with chip tuned engine there is 50-50 chance of the engine or most definitely turbo damage. It is not a questoin how but when. That is it. If you lease the car and will be putting it away in less then 3 years time go for it. If you pay your hard earned money and want to keep your car for a few year and planning on driving over 100k km (mls) be sure that the chip will lower the engine life time a lot.
As I say chip tuning will increase your engine output a little and the car will drive fine. it may blow the turbo in a year, in a day, never, in a half of year.... who knows But again if you do not drive long trips everyday and turn like 50k (mls) a year should be ok. But if the "surgery" is there, it is there....

 

No doubt about it, assuming the tuning turns up the boost significantly, engine longeviety can be affected. Does the turning of the d turn up its boost?

 

i only do around 12 miles a year so i hope that wont be a problem

Yes--that's the reason tuning a normally aspirated engine yields a much lower power increase % than turbos.

 

Kinda agree with that, except the first 2 sentences. Of course it MIGHT lower your turbo life a little bit, dunno if that much about the engine though. I mean it all depends on ALOT of factors like driving style and so on...but yes statisticaly it lowers the turbo life a bit. Let's not get drastic now, nothing will happen noticeably unless u track your car daily or u're a heavy footed,like, all the time. What could one say about a tricked out subaru sti? A super modded supra turbo that puts out around 700-800bhp lasts only 1000km? of course not....
" the chip will lower the engine life time a lot" Yeah and if you really go with the engine tuning you will ruin you engine in 1000km. Don't wanna know what's the lifetime of the evo fq 400!!!! Like2 days...
"it may blow the turbo in a year, in a day, never, in a half of year.... who knows "
Also i don't think there are too many cases that lost the turbo after a day, or a week, or a month, or even a year. If so those were very rarely cases...like a 0,001% chance of that to happen to you. There is a risk in eveything after all, so of course as soon as u start modding your bmw you assume that risc.

[/quote]Yep, what is the actual increase on the d?

 

Just 12 miles? Wow!

 

u guys are actually feakin me out. im having doubts about the chipping
