Knocking after bolt on turbo

[yewly1990]

So yewly1990's problem fix already? Or the engine exploded due to insufficient fueling with full boost in closed loop.

My problem fixed, a/f ratio too lean, and ignition timing not correct by previous tuner.

I tuned my swift BOT at RS too, robyn. I ask him and he said he pulled timing and add more fuel trim at higher boost/rpm/load for safety.That might explain why your knock gone when timing is pulled. I'm using bigger injector oppose to yours 1 extra injector.btw

Try datalog your car and do street tune. I've heard wonders about street tune vs dyno tune.
