Most 225 TT's use an 'H' valve. I believe that the 'J' valve is from an RS4 Bi Turbo.
Im Currently using an ECS race N75 valve. Its alot smoother than anything else and gives a tad more boost than a 'J' valve.
It only goes into limp mode at 145mph, so i never take it that far
I can do any valve bar 'J' for £36.99, the 'J' valve for £41.99 and the ECS rave valve for £49.99 if anyone is ever interested. Postage included too!!
