Firstly, I'm running a wepr ct9 power up kit with a tial f38 wastegate, using a greddy profec a I'm running 0.6 on low and 0.75/0.8 high, on a stock Ecu. It seems sometimes if I'm in high boost and usually if I go quite quickly about 3k revs in 2nd but not hitting much boost(kinda like hanging on the power waiting for the moment to boost it) and when I floor it and hot full boost it sometimes jolts like fuel cut, has a loud backfire, but there is no eml on the dash like I used to get? Surely If this is fuel cut then why am I still creeping with an external wastegate? It doesn't look like it does when I watch the gauge usually but I never watch it if I'm blasting it like that lol My boost controller has a dip switch on the back for 'when overboost occurs' maybe I should try this?
