Yes, increased boost _WILL_ destroy your top hose at ;least, adn possibly 
your bottom hose.   Next, it will pop the end tanks off your 
intercooler.   I'm not saying it might, it _will_.

A preemptive replacement will only buy you a little time.   The stock 
upper intercooler hose is not capable of handling increased boost for 
very long, and it is not compatible with the oil in the intake.   You are 
better off upgrading that hose with TAP's Samco hose, or something like it.

You can get 1.8bar without a spring, but it will build boost a little 
quicker with a stiffer spring.
