valvers will always be more efficent at producing power higher up the rev range, thats where they were designed to produce the power,

also valvers have a problem with maf sensors causing flat spots at about 3500-4000 rpm, a new maf will usually sort this and help it pull stronger through the rev range

mine tails off as the rev limiter kicks in

yes but your valver has a turbo bolted to it does help a little bit

the thing circled in white is your MAF sensor. yes it's its short for Mass Air Flow sensor, and it tells your ecu how much air is coming into the engine, and mostly likely what tempterature too, but not 100% on it. If it's fault it wont be getting the air/fuel ratio exactly right so will run a little 'off'. technical term.

the Si has a fair amount of torque between 3k-4k, which is nice to be able to drive with pace without revving the engine hard. but as tony said, to get a 16v to really get going you need to rev it, and hard i can feel mine really pick up at 4000 ish (hopefully feel it a little more now its chipped)

if you're not very happy with it, give it a general service. it could be plugs or leads not giving it great performance.

id like close to 100bhp with chip fitler and the magnex. doubt it'll be that good though. although it does go better than all the others. ill have it rolling roaded when i can to see whats it chucking out.

brakes are on the list when the 15s are on. 4x4 cossies dont fit under the pimpin' 14s

Is that the best you can do?
-
2000 V70 T5 SE - 2.3, 5 cylinder, 20V, VVT, Turbo, 250bhp, cream leather, climate control, the works!

I whacked some NGK plugs in, and put the lucas leads on, with standard leads but new plugs it was a bit more torquey, and with new leads just felt smoother which is always good!

so yeh i think it quite likes me for changing the plugs now.
