I drive a R34 GT-T and have done abit of modification. Upraged fuel pump, bosch 1000cc injectors, link G4 plug and play ecu, greddy intercooler, kiwagana 76mm turbo, spitfire coils and a GFB boost controller, it was tuned at 18psi or so giving it 266rwkw. Tonight i was giving it a few test runs and there was a loud bang and then the boost has gone right back to about 7-8psi. I looked under the hood and noticed a small tubes clamp has blown off and the tube had came off aswell. i have circled where the tube was in the photo below (it was lowest tube on the top section) and air appears to be pissing out from where the tube was attatched. with it being dark i havent been able to look fully into it all. the car still runs and the only problem (so far) is the boost problem. Any ideas on what blew off the car and any ideas on how to fix my problem?
