Bump for help..?
because I saw someone saying if I run a open dump pipe on stock turbo will have no boost controller, saw someone saying will help turbo breath lot better to gain more hp. so is it true?

 

You can run it but the gains will be minimal with stock turbo.

The dump has nothing to do with the boost controller.

 

ok thank you

 

anyone knows if I have to removed the A/C compressor to install the MAP o2 dump pipe? Because I can see there not much clearance there, also I have aftermarket intercooler, will that be any clearance issue for fitting a MAP o2 dump pipe?

 

No need to remove the AC compressor. The dump pipe will clear it.

 

ok thanks what about the a/c line, heard someone have to bent it a bit for more clearance?? I'm running stock header and stock radiator

 

I'm getting excited to see how it sounds like, do you know if I'm bring it to shop for installation what is the reasonable labour cost?

 

No need to bend the AC line either. The MAP dump pipe was designed as a bolt in piece. As far as labor, that I am not too sure. You could do it yourself if you are up to it.

 

okay thank you

 

Thanks guys so I just wondering can I run dual boost maps on stock evo 9 ecu? Planning on running dual boost maps but not sure the factory ecu can support it?

 

You sure can. See link below.
