Can anyone help me tune?

I have a dsmlink/wideband commander setup and well I'm having issues getting it running nice.

I am also having trouble increasing my boost, I turn up my boost controller but the boost doesnt go up, it sounds like a have a leak but I didnt hear one with my boost leak tester.

Is your MBC hooked up right? If it is try a different one, maybe the spring is stuck inside.

CRAIG

Its the hiss that makes me wonder, its /quite/ loud.

BISS screw :rant:

...Man you are one :censored: weird kid kyle :stick:

Nonetheless, :goodluck:

I love how Kyle is teh Anti Social-- until he needs some help with teh Talon. :)

If you boost leak tested it and it was fine. Then when you put the intake back on and it hisses, I would say there is a leak before the turbo. That would explain why you can't build that much boost. Are you still running the 2G MAF? Check that out first of all if you have boost leak tested it.

I cant hear the leak with the leak tester, but I can without it, its the BISS screw, I need to turn it all the way in to make it stop leaking, but my idle is like 400 RPM now, I have a MAFT blowthru setup so it can be premas leak.

They sell o-rings at Home Deopt that will fix that problem

I might go try ace, that thing seems hard to get out tho (the screw)

use a tiny tiny tiny flat head.

argh I'm trying to, it just unscrews to the point where i can't wedge anything in around it.

if the car drives bring it by.

Drive it by huh?

So kyle.........gonna do that? :stick:

REMEMBER :naughty:

It was my TB gasket, it was backwards :uh:

So how didn't that leak when you boost leak tested it?

CRAIG

I don't know, but it couldnt hear it unless teh car was on, maybe it was a big enough leak that it was silent unless there was a ton of air being sucked in, I wonder if thats why I couldnt boost very high? :confused:

Huh, I didn't even know you could put that gasket on backwards. I thought it was just flat. If I remember correctly, the BISS is a phillips head. I believe I use a magnetic screw driver to pull them out. They unscrew and do not reach the top of the hole for them.

Biss feels plastic, and its the gasket between the TB and the manifold, it has a tab on it that needs to be facing towards the front of the car, it blocks some passages for the BISS i think.

couldn't you just turn the idle set screw in all the way if it is still a problem then change your idle on dsmlink til you figure out how to fix it?

I found the same leak on mine last night. I had replaced both TB baskets. The new one between the TB and manifold that I got from Mitsu is symetrical so you couldn't put it on wrong. Well it didn't seal. Dug the old one out of the garbage (which has the tab like you describe) put it on and all is well. So much for being a good boy and replacing gaskets. :headache:

That is what I thought. Mine are symetrical also. I bought them at Mitsu. How about using some RTV?

Try just straight RTV without a gasket. Gasket + RTV sometimes doesn't seal as well as just RTV.
