sheesh i should hve stuck with my i-vtec accord.

A much better built motor thats for sure

I don't like them, there a bodge.

They take the common rail pressure signal and feed the ECU a modified value so the ECU thinks the fuel pressure is lower than it is, the ECU consequently extends the injection pulse, delivering more fuel and hopefully more power (or smoke!).

The maps are crude, they make an assumption of engine revs based on the rail pressure (its fed by an engine driven high pressure pump so is slightly related although this varies with age and wear!).

A proper map can do so much more, it can up the turbo boost, give much greater control of fuel quantities, possibly disable EGR, vary power based on throttle openings, speed etc etc etc

Just as Mark says. I went down the plug & play route at first. There was a gain in power, but also smoke
I wasn't happy & neither was the tuner.
I was recommended a tuning specialist who did a proper remap to gain extra boost etc. He also found i had the wrong MAF sensor fitted.
It was like driving a completely different car

Boxes I think are terrible, they're literally a very dodgy way if getting more power but usually end up causing more trouble than anything else. There is a 58 plate Astra Van in Ashford which runs a box, it's smokes terribly, seriously if you drive behind the van you struggle to see what's in front of you it really is that bad. Get a proper remap done and it'll be loads better, also get a de-cat done, this will give you some extra go power and because it's a diesel no emission trouble come MOT time.

A proper remap and de-cat and it'll be much better. Avoid the boxes.

Been in touch with the dealer I bought the car from, they have 16 people on the waiting list for my car, so Im going to sell, I dont like this particle filter scenario at all.

looks like Ill have to put the omega back on the road til I find a replacement.
