There is a rissistor fitted to some wires around where the sai is supposed to be but dunno where the n112 is??
Hmmm, Usually the resistor is to stop the fault code, but im not sure whether it would have an effect on the running of the engine.

DId you try with a NEW N75 valve?

Have you tried unplugging the MAF to see if this changes how the engine reacts?

I presume you have a Forge Actuator.....How have you got this setup in terms of preload?  Running a yellow spring now yeah?

Any misfires or is the low boost continuous across the rev range.

You are uncertain as to whether its been mapped?

Where are you taking your boost reading from?



Yeah put a new brand new n75 in.

Yeah tried the unplugging the maf and doesn't do anything

And yes I have the forge with yellow spring and have 3 full turns of preload

And no the are no misfires although the exhaust sometimes burbles and pops a little when releasing off the accelerator

And yes as I didn't map it myself although it does seem to quick to e 150hp

My boost gauge is tee'd into the fpr pipe.

Cheers guys

I yeah and the low boost is all the way across the range but if I let off wait a sec and then power on it sometimes goes back to 10 ( which I still think is low especially if it's mapped)

Really?
Doesn't limp mode reset when you turn it off?
Another thing don't know it was because of the cold or not but my traction control light wouldn't turn off and then did after turnin it off and on again????

I thought limp mode made it really slow as it isn't that bad really still keep with beakers etc just doesn't feel like 200ish horses

hmmm, maybe something limiting it for safety then...

I still think the EML will be the first thing to sort out though

doesn't really seem like a leak to me, a problem with the throttle body perhaps? to be honest you're shooting in the dark without some decent diagnostics/data logging.

Well it's says its the sai but when I reset it it doesn't perform any different.

Yeah I thought that and cleaned it but no different.   :sad:

I have and can recommend one of these http://www.ebay.co.uk/itm/VAG-Car-Diagnostic-Scanner-Fault-Code-reader-/160717750851?pt=UK_Diagnostic_Tools_Equipment&hash=item256b864243

Is that just a engine code reader then? Or can you do other stuff?

Cheers
