Ever wonder what happens if you hit fuel cut at 26 PSI on a turbo RX-7? Watch me do it on accident while tuning. For those wondering, I had the ECU set to 20 PSI expectation and wastegate to 26 PSI. ECU will go 3.5 PSI over its limits before it cuts the fuel. Small logical error can make a huge difference. I got lucky. I attribute a large part of that to the pre turbo water injection keeping my knock low and combustion temps low while tuning.
