Poping and Banging
#1
Change my ECU a few weeks and the car has started poping and banging,It only happens when i come off the gas and slow down with a bit of brake. when I put the old one back on no problem.But the new ecu gives me better mpg and more power. sound okay, but do not what to do any damage. Have a couple a engine upgrades. ECU,Greedy dump valve,De-cat exhaust.HKS Induction. Any Ideas ??? Or is this normal?

Chill mate, the pops and bangs are natural for an upgrade in the ECU, your car is probably running richer and with higher boost which means you dump more fuel on the over run and it's burning in the Zorst......... tis the nuts mate
