Just dynoed a stock RalliArt here at the shop.

Not nearly as retarded rich as EVO Xs:

Kind of goofy stock boost. It is an early car so I imagine it would be better on a production car. It had the same spike in street driving. It would kind of waver and cycle, rolling up and down till about 4K. A longer pull on the dyno smoothed it out. That contributed to the quicker spool. That would be the spool you would get by putting it in 5th and hammering the throttle to the floor and hanging on till you hit red line.

Injectors are nowhere near maxed out. Only 70% duty cycle vs the EVO Xs at 95% stock according to the ECUTeK logger. There should be room for much more power when the boost is raised.
