FORCEDG6E Member 145 Member For: 13y 6m 25d Gender: Male Location: adelaide Posted 07/06/14 11:14 AM Share Posted 07/06/14 11:14 AM Just wondering if anyone has some advice for me.I have a g6e turbo tuned 98 with 300wrks. I had an issue with backfiresing at high rpm/boost. I fitted walbro fuel pump as I was told this was the issue. Backfiring is still there but about 40 mins after pump was fitted I started to loose boost. The boost come on very slow and only about 12psi when its tuned to 17psi. I have checked all hoses and smok tested intake/cooler pipes no leakes. Ive cleaned boost solenoid and checked for exhaust leaks. Fuel pressure is 400kpa with vac line on at idle.Im.stuck now dont know what else to do any advice would be greatSent from my SM-G900I using Tapatalk Link to comment Share on other sites More sharing options...
