I think its depending on your map - some maps are done differently - i think custom coding can map your ecu for power through different revs -

Or

The n75 J valve has been known to hold boost a little longer and boost but ive never tried it

Some cars like it, some dont(i.e limp mode) -

Have a look on the net for N75 J

Is it a boost leak?

[Sharky_82]

apologies, i was under the impression he meant in general - how to gain extra power at top end of revs -

as per above - you having any issues with your car?

noticed anything different when driving

I've heard of owners in america adjusting the vane actuator so that it holds boost at higher revs, but I reckon this could cause limp mode, so you might need to get around that if you went down that road. It sounds like a simple idea that would then lead to other problems. Do plenty of research first!

[Sharky_82]

actuators should never be touched because they are electronically controlled - as you said, limp mode -

which is what my car has got at moment - bloody annoying!

thnx guys.

it got the ko3 on it at the mo, iv just put a forge valve on it and theres so much boost from 2 till 4500 rev it lights the tyres up for fun, but after that it dies away. il try that n75j out is it the 1 off the tt225.
