And 199lb/ft torque. 
Until you change the ecu for an Mtek one that is... 
What are the likely figures with the mtek chip?
Phil got 265lbs ft.
No disrespect but I find that figure VERY unlikely... it's over 30% increase over stock, which is simply unheard of with just a remap on a N/A car. It's not like these engines are particularly under-tuned either, they're producing a healthy 67 lbft per litre. How that can be increased to 88 lbft per litre (which would be a fantastic output for an N/A car) with just a chip just doesn't make sense - all you can do is change fuelling and timing. I'd say you'd need a fair bit of work to improve the airflow, such as hotter cams, better exhaust manifold (which I believe is a known restriction on the Omega), probably complete free flowing exhaust system, possibly intake mods.
Unless the chip has also moved the torque further down the rev range (unlikely, usually they push it higher to maximise power as Mark points out) then the power output must be touching 280 BHP!
I expect that figure was obtained on a chassis dyno and "back calculated" to flywheel figure, a method fraught with assumptions and their associated errors. I don't doubt that the chip is very good and there have been a few positive reviews on here, but if anyone buys one expecting more than a mild power increase coupled with driveability gains I think they'll be disappointed -- 30% torque or power hikes just don't happen from remaps on N/A cars unless there was something badly wrong with them to start with.
For clarification, on 25th November at Jamsport, my car a 3ltr MV6 with M-tek chip came back with 228 bhp and 262 ft/lb torque
On 17th Feb at Northampton Motorsport it came back with 244.4 bhp @ 5853 rpm and 233.3 lb/ft @ 5009
So yuor guess is as good as mine as to what its knocking out, nothing was done to the engine between rolling roads, apart from 3k miles.
I think the Jamsport figure is more acurate for BHP as Northampton Motorsport say i loose 87.5bhp through the transmission. Also on the same day, Sir Sideways 3ltr auto which is standard came back with 247bhp and only an 81bhp transmission loss
Basically running an auto is difficult on a rolling road as you cant dip the clutch at the red line, unless you have the correct software to compensate, which Northampton didnt appear to have.
Worth noting on the same day a 3.2 signum that has been re-mapped and was reading 230ish at Coutrenay 2 weeks before only made 213bhp, and most other owners felt the results were 15-20bhp down
But ill be in Total Vauxhall with 244 and 233 so i dont realy care as it looks good!!
