Better response and smoother powerband
If you blow a charge pipe you can still drive the car wherever you need to go unless its the one between the throttle body and maf
Run the blow off valve open atmosphere without having the car go rich as hell for a couple seconds.
Ive always ran my maf setups in blowthrough and never had an issue. 550whp at 30 psi on a 60 trim turbo setup and no problems. Never had a maf go bad from it either. I was running a z32 maf. But ive done many setups on stock mafs in blowthrough as well and again no issues.
