So today I recently installed Ets LP2 and short route upper intercooler piping. The car ran perfectly fine before I installed, but I'm thinking o FFF'd up something. Everything sounds good until I try to boost and it sputters and kinda backfires. Wont let me get above boost rpms.
Mods I have are full turbo back, boost controller, and tuned. To change the UICP I did remove the entire intake but im stumped?

 

major boost leak is what it sounds like.

 

You installed upper intercooler piping? You have a leak.

 

Yep what they said. Double check connections at the diverter valve/BOV, vacuum feed hose, and connection to turbo inlet snorkel/intake.

 

Yeah that was the problem, clamp was loose. But what a difference even with the stock intecooler and intake. I got the short route upper and fitment was a little tight with the stock airbox. Boosting is a little quicker.though, really happy with it.
