Need help!!

I just installed VRSF intercooler and catless DP. When in neutral if a rev the car it's sounds fine but when I'm driving and try to accelerate hard I get a whistle(like air scaiping) this only happens when I drive it. Checked the dp connection with th exhaust and no leak. What can be the problem?

If it's a super airy noise there is a leak somewhere. It's when boost comes on that all the air is escaping somewhere. Check the connections on the DP again, there could be a small leak there.

Whistle, likely the intercooler connection. Make the sure couplers are squared up, straight and above all, tight.

Intercooler connections not tight enough would be the first place I look.

That sounds like a boost leak. My leak was between the charge pipe and the up pipe from intercooler

Kevin39 · 12-14-2016, 08:17 PM

Yep, happens to the best of us. I turned the boost up and blew the pipe off the passenger side, put it back on, then blew it off where Orteeze did at the charge pipe. I had to tighten the connections a lot more than I thought I would. Mine didn't whistle like that but you could tell something was wrong just by the lack of boost.
