I have bought a gtr33 and I'am loving the grip and most things about. It is definetly the best car I have ever driven(trying to get all my mates to buy one now:chuckle: )

The only bad thing is there's so much lag. Its a 2.7 on 2540's and 282cams. Nothing really happens till 5000rpm, then 6000rpm is where it all goes mental.
Anything I could do to get the power coming in earlyer without changing the turbo's or cams???

Well 2540's are quite laggy.......although they are well suited to a 2.7.

The cams are a very high duration too.

Options are smaller cams, get it remaped and request you want it more livelier in the lower rev range.......timing and fueling can all be set to help this.

Failing that go for some slightly smaller turbos that are better for street use.

The list is endless and you will find loads of info via the search facility.

Good luck.......let us know how you get on.

Welcome to my world! :D
Having been through this myself, although different set up, it seems as though having the car mapped to the correct spec and requirrements will help a lot. Im assuming the car hasnt been mapped with this set up as yet?

As Lamb said, id of thought the 2540s would have come on earlier than that on a 2.7.

The car has a power fc and it is mapped on this set up.

I thought it would spool up quicker with the 2.7 too.

I would get it mapped mate.
I have big twins on my car. Full boost at 4800 rpm.

Must be something wrong with your map.
