So I just did a dyno run on my supposedly "stock" 20vt.
No idea if these increases power In any way, but I do have an FMIC, K&N air filter (in the airbox), ngk spark plugs and a custom stainless steel 76mm (3 inches) exhaust with a cat, middle and back pipe (downpipe is still standard).
I have not made a custom map for the car as I need to get other things sorted first, but I did do a dyno run on it.
These are the results.


Am a bit worried about that drop in both power and torque in the lower rpms. What could be the cause of that?

Also, my bov is completely knackered and it's making silly little stututu noises, which I really enjoy but I am about to fit a new bov. Don't reckon that would be the cause of that drop in power but I wanted to point it out just in case.

Whether stock or modified that chart does not look normal. However the corrected max numbers of 200 BHP and 275 NM don't sound far off (excuse 20 year memory fuzz)
