700 whp! Element Tuning Hydra, Hydramist, 07 STi, 1600cc, 92 octane and Q16

I had tuned this really beautiful 07 STi once before but we ran out of fuel so this time around we upped the fuel injectors to 1600cc so we could really see what she had.

For some reason all the dyno plots this time around had the chop during spoolup on every car I tuned so maybe next time we need to adjust the ramp rate.

Like clockwork this time the car tuned easily and without issues. First up was the pump gas and Hydramist which netted us 604 whp which is pretty nuts for a daily driver! Next we ran the new 1600cc injectors with Q16 and the Hydramist running 80% water and 20% methanol. Slowly turned up the boost, dialed in the AFR and a really easy 700 whp.
