ive seen on ebay someone selling "OPEL VAUXHALL V6 X25XE chip 191HP"
is it possible to obtain 191 bhp from an unmodified 2500cc motor?

I would say that is a bit too ambitous without cams etc
-
iv read this one tb and it claims it's with the standard cams but think it tricks the maf and rams excessive fuel in.
quite fancy one of these to make the most of the 3.0 cams
*edit- i'd expect at most 15 bhp increase based on remap figures

I would steer clear of anything that claims to "trick" the ECU. A proper chip will replace the map in the ECU rather than try to trick it from outside.
Also, remember an engine is not a bonfire. Chucking more fuel in won't give you more output, just poor fuel consumption and knackered cats. The MAF already measures airflow and gives you the right amount of fuel. It will automatically give you more if you change the cams, and airflow will increase. Tuning chips work mainly by giving a less conservative ignition map, not more fuel.
I wouldn't expect more than 5% more power from a chip change. Not on a naturally aspirated engine, anyway. They are already tuned pretty well as standard these days. 3.0 cams in a 2.5 is apparently a much more worthwhile mod though.

"Tricking" The ECU will flag a MAF fault lol and god knows what else! these chips wont give hardly any power! chipping a N.A. Petrol engine is a waste of time and you may as well give the money to a homeless person much better spent then!
i wasted £200 on a proper chip and it made no difference what so ever infact my car was worse on fuel! didnt go any better and was running very rich!
Chipping a TD is well worth it and a Turbo petrol but not N/A engines!
