my boost gauge taps into the FPR hose so if it blows off it's obvious by the boost gauge.

 

430WHP in DLL with AFR's in the 10's and boost around 26. I will post again when I am done tooning.

I never thought about it that way with the boost guage hooked up to the fuel pressure vacuum line. I always stayed away from it because it seemed like it just created another possibility for a leak in the line. Never thought about the fact that it would show up on the boost guage. Anyway, knock on wood it's not coming off again now. I find it kind of weird that mitsu doesn't put hose clamps on it from the factory.

 

nice and a conservative AFR..what's your goal for that setup on pump gas?

It was getting pretty crazy with vacuum leaks when I started pushing 30psi. I went around and zip tied every single vacuum hose on my car, haven't had one blow off since then.

 

Good info on the vacuum lines. Hoping to hit 450WHP by leaning it out to 11.5 to 1 at 26psi and running that for the road courses, maybe even a little less boost and power. Will see what the EGT's and knock counts are on the track. Want a street tune pushing 30psi and 500WHP on pump. We shall see....

 

I was around 460awhp @ 26psi as well with the HTA 35R before pushing it on up to 30psi and breaking 500awhp. The fun factor goes way up on these cars doesn't it
