Ok like the title sugests Ive just had a new 270ltr fuel pump fitted..Happy with it, ran fine but first time I pulled away hard in 1st and 2nd it was overboosting. HKS evc was set at 1.00bar and it hit 1.3ish and beeped. Gauges hit the same level so not just the evc, but this never happened before the new pump...any ideas people??
