Hey guys, just for reference, the post above IS correct in terms of the 044... My car ran 360.7kw and the pump was pretty much on its limit... It is in the tank and is dead quiet (a big surprise to me) and i couldnt be happier! For those running an R34 the fuel pressure gets a bit sketchy at that HP but there is a modification that can sort it out, the boys at JEM sorted mine out and safely ran it back to 357rwkw which is the final tune
I was a bit worried about fitting an 044 to my car for daily use, but now that its in and ive driven it i strongly recommend them
