Well if you have no engine management then thats why your seeing higher boost levels from installing a TBE. You not getting boost creep,you are just flat out over boosting. The wastegate code is due to the overboosting. An ECU retune would fix this.All I've got in there is a full turbo back Greddy exhaust, that's pretty much everything performance wise
A lot of people run stock injectors on a StageII (uppipe / turboback / reflash) setup.04WRX_wagon said:So then if that's the case, along with the retune, would I have to upgrade my injectors as well or are the stock injectors good enough to handle the higher boost levels??
