Run a quick 1/4 mile, I don't do well with dynos but would like to know what it does run with those mods

the title of 400+hp kit is based on BHP not WHP.
technically when they're hitting 330-340whp it's a bit over 400bhp but going low at 400 is covering their bases in case someone's tuner poorly tunes the car.
or in this guys case......tunes it and makes it read about 40whp higher than it should.
