This is a known problem for the 1.4 turbo Fiat engine, we have addressed it with a fix that solves the issue!!! After extensive dyno and street testing we have found that this fix gives:

Higher held boost to redline
Better part throttle boost control
Much smoother power delivery in all throttle applications
Gains up to 5% increase in power

We have yet to see a check engine light with this solution in place and here is why. The check valve has a very low cracking pressure (.35hg) and a very high flow rate (12cfm). The combination of the low crack pressure and the high flow rate keep the CEL's away.

We have also outfitted the valve with a filter and the reason for this is because we have seen a very low vacuum pull on the valve when the system goes into EVAP testing. It took about 120 miles before we were able to enable this test, but when it did start testing the EVAP system we found that there is a pull of vacuum on this line.

This valve helps so much with the boost control and smoothing the power delivery that every 1.4 turbo Short Ram Intake and Cold Air Intake we offer for the engine will come with one!

Its the best dollar per performance/drive-ability part you can buy for the 1.4 Turbo Fiat engine!
