Well i replaced it all tonight, made sure there was no splits, etc, the old crappy clear stuff actually had no leaks, and with the silicone and resiting the t-piece to as close to the inlet manifold as i can i still have the same readings, so i conclude either a shot gauge or a boost leak somewhere else, but where any ideas?
 
Shot gauge. Has to be if the car doesn't feel any different.

Thats what im thinking aswell, cos its been the same since i had it, if not got more responsive with the few mods i have done it, either that or its always been running a small leak somewhere, in the back of my mind i hope its a leak as then there is more untapped performance for me to play with.
 
Gauge changed for a shiny new one, still the same reading, so im out to the stealers at 4 to see if they can see anything on there comp, hopefully its a quick fix like a dodgy N75 or something.
 
Ok turns out ot was the n75 and it had been faulty since purchasing, hence why i havent noticed a difference in performance, now its a different car, getting 15 PSI peak holding 13 feck me its quick, the smile has returned. Love my LCR ;)
