I have bought a chip set off eBay for about 60 pounds. The seller says it will give my omega 2.5TD an extra 35 bhp on top of the stranded 130 bhp. I have found a mechanic to install them. Has anyone done this before? Could it damage my engine? What would be the best thing to do?

As 2.5 TD is de-tuned, theoriticaly possible..But practically not sure..

Some people here may know about the upgrade chip models and codes..

Post up a link to the product....

2.5TD is chippable. not sure of the actual figures, however, if your car is an auto and is on the original AR25 box it'll rip it to shreds due to the extra torque.

Dos anyone know of someone who has done this before? And how to I upload a picture to show you?

He says it will add 170HP and 330NM. Its called X25DT chip. Here is the link to eBay- www.ebay.co.uk/OPEL-VAUXHALL-2-5-TD-X25DT-chip-170HP-330NM-Omega-B
 if that doesmt work just type x25dt into the eBay serch.

page moved..

Just type x25dt into the serch bar in e-bay and it should be easy to find.

Just checked the feedback page..possibly will work..Lets see What  TD experts think.

I fitted a "Tunit" box to my '94 2.5TD Auto. Took about 20 mins to fit and get it adjusted. That knocked it up by 30bhp. Big difference in performance...'til it blew 3rd gear. Yep, the AR25's don't last long if you increase the ponies, but it sure made me grin...for a day or so !!

If it's a manual...go for it !
Once you stop using the loud peddle so much and drive normally you should also see about a 10% saving on fuel..apparently.  I didn't get that far to speak from experience.  Put "Tunit Diesel Tuning" in a search engine.  

Chipping gives about the same performance gains, works out a fair bit cheaper to buy and fit, but can't be returned to std so easily.

Its likely it can add that much preformance increase......but I am yet to see a diesel ECU with a socketed EPROM, every one I have done required the old chip de-soldering and a socket fitting.

So I am assuming that the soldered chips are not SMDs?

No, through hole....

That sort of figure is achievable, though I would have gone through a member here, Omegatoy.

I have a chip fitted in mine, and it was soldered, so Mr DTM had to fit a socket for me.

I went for a chip that is the best compromise of power/economy, which should be around BMW spec (140bhp ish).  Just for a laugh, I may try a more powerful one soon, simply as it has to be done!

If you have an automatic gearbox, ANY chipping will melt the box unless you have put a strong one in...
