Conversation Between The Alchemist and pwr-346

cheers. tial seems to be the choice. its also less than half the price of the race valve for me. The way i see it, the proflo a butterfly valve, it leaks, its bad. hoping to pick up a little.

Well, the easy way to see if you will pick up boost is by pressuring your system and seeing how much air is leaking out the Proflo valve. The TiAL valve doesn't leak at all, so it's worth changing in my opinion.

hey mate,

im running a d1sc on a ls1 commodore here in Australia. im making about 10/11psi on a stock engine with valve springs and 1 3/4 headers wondering if you picked up any boost swapping from the proflo valve to the tial q. im also having stalling issues and im thinking its bypass related.
