I would ask on another forum tbh. Not putting this place down but it isnt full of LET magicians really.

Also you would be best off getting it setup & monitored using a wideband lambda.

ive had a good look through so many differant forums an theres so many differant oppinions on wot to do.. Lots say vxrs overfuel an dont work wen others say they work perfect an power safley up 2 400bhp... Ive seen alot say that evo5 software is set up 2 run 440cc injectors- is this true? Confuses the **** outer me as theres so many people claimin differant things.. :confused:

Only a wideband could tell you.

Taking someones word at say 3bar & setting it isnt a guarantee.
IMO if you can afford that spec a £170 Innovate wideband kit is essential.

Much like building a 300bhp track car & fitting cheap ditchfinder tyres....

i will get 1 at some point i was just hopin that some1 had built a very simular spec that i could get a rough idea from.. Will be changing 2 standalone in futre also so just looking for a start..

As Craig said, the only way to know for sure is a wideband. No two engines are identical so its really not worth the risk taking someones word for it.
