What's the problem ?http://www.pistonheads.co.uk/sales/1423607.htm
40% is maybe a little optimistic, but there are real gains to be had out of these modern petrol turbos, simple increase to boost and fueling see's significant gains, look at the vectra vxr's for example most guys are running maps 300hp (a 20-30hp gain) and 400lbs of tourque which is over 110bls over standard.
a mapped vectra is just a quick as a stock cv8, i know from experience!

UP TO UP TO UP TO UP TO UP TO
it didnt say every car might achieve this. It sayd UP TO, which can mean anywhere from 0%, UP TO 40%
However, in order to make that claim do they not need to have gotten those figures from somewhere?it didnt say every car might achieve this. It sayd UP TO, which can mean anywhere from 0%, UP TO 40%
Else there could be a hard limit of 30%, in which case it would be 'up to 30%' not 'up to 40%'.
What I'm saying is that if 40% is unachievable in ALL CASES then surely that's false advertising?

up to up to up to, yes, upto monkey business. It claims available for most VX range (doubt vxr8!!) but is that up to 20% more power and up to 20% more economy on the same car, or a mixture? How can you get 20% more power and 20% more economy?
Don't know about 20% of each, but it is definitely possible to remap a car to get more power and better economy.For example my Evo fueled very rich as standard, but by leaning the mix out a bit you get more power and more economy. There is an increased risk of detonation, though, so it has to be run on high octane fuel. A lot of guys with highly strung engines will also use an exhaust gas temperature gauge to monitor temps (as lean mix burns a lot hotter) and a lamda gauge and sometimes even a knock gauge - just to check it's not been pushed too far.
In essence you can have more power and more economy, but the trade off is reliability (maybe).

yes I know all that but 20% power and 20% economy and as for leaning out unless its done on a custom level I'd rather not take the chance in a petrol car

not if its done properly (ie decent tuner doing a custom map)
i wouldnt really trust one of them boxes on a petrol turbo.

Anything with a turbo can have the power upped by winding the boost up its just a case of weather the engine is strong enough to take it. I have over 68bhp more than stock with more boost and have seen even higher gains in the past.
Got to ask, would you just have a map blindly put on from someone or go for a custom map? (strange to ask as I know many here have off the shelf tunes but I'd not want to chance it with a turbo)stigmundfreud said:

I did get it rr at srr after putting the map on just to make sure there were no issues with it going lean.
