I’m hearing a loud series of pops at redline when WOT

[Babaroga]

JB4 Tune 93+ map, bms intercooler, BMS intakes, 2 step colder plugs, occ, exhaust cutouts

Exhaust cutouts are mounted at the first bend of the exhaust from the manifold.

If someone could read this and let me know if it’s something in my tune or possible backpressure problems?

Also losing boost if I ride w cutouts open for long, have to close cutouts and turnoff car for it to come back…weird

 

[ChaneRZ]

Overboost due to exhaust cutouts. Significant timing on current octane. dial it back down to map 1.

Could I run same map with cutouts closed? What all do I need to run higher maps reliably?

 

[ChaneRZ]

Yes try running it closed. If you really want to run them, install the ewg wires. Might mix 93 with some E85 for a total mix of E30.

does stinger have a rev limiter? My hot rod used to do that when I over reved. Never over reved my stinger

I think it cuts fuel if you try to exceed redline. It will upshift automatically anyway, unless you have the traction and stability control off, then it will just cut the fuel and stay in gear. Only did that once and I try not to drive with stability control off, even at the track, so If I forget to shift, car will do it.
