i ran this for a few months with no issues, same with a few other guys.. really i would just take some timing out in the high load low rpm range an you should be fine..
Actually I have been running it for few months now and I like it, my car averages 6.2L/100 km on the highway (Hybrid territory) and on the track I can keep up with STi's on the straight away (B15 tranny). I fill my car up with 94 octane to be on the safe side.
Can't think of any other car which has amazing mileage and power balance.
for shits an giggles let me modify the al fred.bin timing map an send it to you to try out.. i bet you gain some low end.. its only the 3400-4400 range where the timings a bit to high..
