There is certainly nothing wrong with going this route, but lets take a good look at actual WHP output.
The Stage 1 is rated at 280 DIN, which is 276.2 Crank HP.
The Stage 2 is rated at 310 DIN, which is 306 Crank HP.
Though when you factor in ESS's drivetrain loss of 15% for the WHP calculations, things go downhill quick. Most would agree that a 17% or more drivetrain loss would be even more realistic on a rear wheel drive car.
Then of course this is all being done on a Dynojet dyno, the highest HP producing dyno out there.

276.2 X 0.85 = 235 WHP, or at 17%....276.2 X 0.83 = 229 WHP
306 X 0.85 = 260 WHP, or at 17%....306 X 0.83 = 254 WHP
