Waste of money and inferior than the stock boost control. 2 minutes ago, adams355 said: Will the standard exhaust and cat be able to handle 14psi? Yes. 3 minutes ago, adams355 said: No where to do the 3rd gear run A dyno seems like a good place for that. Link to comment Share on other sites More sharing options...

I saw some posts on here about decent manual controllers getting to boost quicker? I can get 14psi in second gear at 50%+ throttle. Will the stock boost control be the same (sorry just a newb to turbo). Its strange Autotech tuned it like that... Link to comment Share on other sites More sharing options...

So if your actuator currently can't hold the desired boost, changing the boost controller won't help. Providing the hardware is up for it, the stock boost control can come in as hard and fast as the hardware can provide. 2 Link to comment Share on other sites More sharing options...

The main difference is that it can change the boost curve as well as boost pressure according to temperature. Link to comment Share on other sites More sharing options...

I think it may be the exhaust and standard cat stopping it from holding boost, but I'm not a 100% sure what's going on there though till it goes on the dyno. Thanks for reply's.

Have a read of how an ebc works and have a read of how a bleed valve works. An ebc will bring on a turbo quicker and more accurately than a bleed valve. The falcons run an ebc.

Perhaps other parts or wiring needed fixing that the owner wouldn't do so the shop went with it? It might have already been fitted? A coin was flipped? Someone said a shop tuned it but it was never tuned at all? A guess is just that though, a guess. I could list more reasons why but it's kinda pointless seeing as I don't know for sure.
