Your missing the point here chaps...

The person making thne error here is YOU LOT

For the last time...
The pump will probably flow enough fuel for 500Bhp. But NOT on a YB

Now how theyve chosen to word the advert is not my business, and for teh record, i think its fooking sly and have in fact told them so on behalf of a customer. Their official line is.. "the advert is a mistake"

I can only reitterate one last time....
Ring them and ask what it will flow at 5.5bar. That is what pressure you are asking it to flow the 500bhp of fuel at with 2bar boost. The ITP 048 struggles with 370 at that boost pressure, unless your tuner runs extra fuel pressure in which case it may not even flow 300bhp at 2bar boost..... lol

Its sly advertising folks, and just shows thata little knowledge can be dangerous. Be carefull out there
