in that case it will be the solenoid, do some reserch on the rats nest and re do the lot, or go non seq.

i think carl haywood still does the conversion for a good price and he will reverse it if you dont like it. i found it much nicer to drive and a lot less hassle as i didnt need all the rats nest.

okay. but i live in Finland sooo making any mods by some others is quite alot impossible.

ahh ok bud, sorry i didnt see that.

there is loads of info on the rats nest if you search, but its not to be taken on lightley.

Definatley the 2 solonoids at the front of the plenum mate!! No need to remove the upper intake manifold. All you need to do is undo the strut brace, & unbolt the top pressure tank, then you will see 2 solonoids held to the plenum with 2 10mm bolts, these are the units you need to chainge.
The right hand one (as you look in to the engine bay from the bumper) controles your boost & the left one controles when the second turbo cicks in!

Mine was duff & I was having exactly the same problem..... perfect boost all the way to 4000rpm ish then it would just drop off as te RPM\'s increased!

Attached is a pic of the unit you are looking for! It\'s the 2 square boxes at the top left of the pic:


Here is where they live when everything is together in the engine bay (Units are marked with white lines):

actually they control the turbo pre control and waste gate, the problem sounds to me like the charge relief solenoid which i think is on the top of the rats nest at the front, but if one is starting to go the rest aint usually too far behind.

ok so i\'ll be changing all the 3 mentioned above. i would think the charge relief solenoid aswell, as the boost is coming out of the valve itself, even with the Forge one. WGT has them. Used intems but who cares if they work ok. I think i\'m goint to remove the airpump aswell as it\'s there for no reason now. the top hose is plugged and cable is hanging. was it only the blanking plate kit and pulley kit to remove it?
