Thought I'd get a recent chart done as a before and happened to compare two curves between a factory paper panel and a K&N panel. Interesting result. Unfortunately it was tainted by the aircon being left on for the paper filter run. Happy to say that the car pulled almost the same as what it did Sept 2003.

I'm not entirely sure what the kink was caused by as the rpm at which it occurs is 1000rpm past where the aircon unit supposedly turns off. Hard to say. Anyway, when I have my next run I'll make sure the aircon's off.

Blue is K&N, Red is paper.

Nice work dude! :D

Damn boost, I mean aircon button lol

Back in Nov I had my car dyno and was found to be running very rich. At that time I had ran 161Hp at the wheels. Since then I swapped out the cat for a highflow cat from Maganaflow, reaaranged my O2 sensors and had an Apex S AFCII installed to deal with the A/F ratio. My dyno went up to 181 WHP and 198 Ft/Lb Torque

Having your air/fuel ratios graphed is a nice feature. Wish the dyno place up here would do that. IMHO that's better than getting torque graphed, especially if you're getting a chip tuned.

My biggest problem is there is almost nothing in the way of competition up here so what dynos do exist are very old and probably poorly maintained. I only know of two dynos here, though a new performance shop has opened up so they might have one too, I haven't checked yet..

Anyway one of the dynos is a 4 wheel dyno and they charge $100+ per run, even in groups, so they don't get my business.. the other guy charges between $40 and $60 per run which is better... but if you want an AFR reading you get it in real time during the dyno run - his old software can't graph it :( or he doesn't know how to turn it on, one of the two lol oh well.
