Turning boost down without retune?

Hey everybody. I just installed my intercooler and upper pipe and can't seem to get the clamps tight enough. The coupler keeps popping off the intake side of the intercooler when I go above 20psi. I have tried everything I can think off. Super-tighten the worm clamp. I got a t-bolt clamp from autozone (it is too big and it sucks anyways). I even tried two clamps. But every time I hit about 23 psi, BAM! off goes the lower pipe and slams into the ground.

I'm heading back to Lubbock tomorrow and I have to take the Evo. Is it OK to turn the boost down to like 15psi just to keep my lead foot from blowing the pipe off? I have a Hallman MBC.

Thanks

its safe to lower the boost but not safe to turn it way up without a tune.

If you get the clamps tight OVER the lip they wont come off. I did this with my ETS kit and never had a problem. Maybe your clamps suck, I use the ETS clamps.

You'll be fine turning it down, but go get some Tbolt clamps for all the presurized points, you will never have that issue again. I have NEVER had a pipe blow off, even at 30 psi.

Thanks for the responses. I'll turn it down when I get home tonight.

I got the AMS intercooler and the lip on the pipe sucks. I'm kinda surprised. I think I also need to adjust my LICP to sit closer to the intercooler.

I'll be getting some t-bolt clamps when I get back. I just don't have time before I leave tomorrow.

KevinD, add some clamps to my order.
