I would assume that running at such a high boost level would require some fine tuning and also some pinging nightmares..

I have the feeling (in my ***) (no, not THAT feeling) that the 01 with VVT etc has more power on the top end... and while I have no graphs to prove this, I could draw one with a crayon and scan it, but I am not going to...

so I would argue that, for example, 2 cars, identical aside from engines, 1 a 99.5 with apr v3 and 1 a 01 with apr v3... and the same drivers with the ability to do EVERYTHING identical, the 01 would be a HAIR faster...

but I am not betting the farm on anything... then again, I don't HAVE a farm... but you know what I mean

I need to go home... too much work...

I dont get any pinging with the one I race with or the ones I use on the streets with pump gas. GIAC does not sell this chip to the public and I do alot of testing for them. The most you can buy from them for the K03 is a 1.1 bar chip. But they do sell a chip that runs 21psi and peaks at 26psi on a full load for the K04 kits from DSR for the dbw cars.

You have to compare both dbw cars. They use the same size turbo and injectors. The older cars dont.

The newer engine has a bigger compwheel, .2 lower CR, VVT and I forget what else.

what about weight differences?
