Cheers Ben. It is laggy but I haven't really been in any other gtr to compare it too. I don't find it that hard to drive As I only drive it to and from work. I think full boost is about 4500rpm but it's only limited to 7000rpm at the moment with plenty left in it. In 2wd pretty much useless with stock rubber. Pulls hard in 4wd tho. There is no e85 on pump here that's the only reason why I haven't done it...
