i finally got chipped......post-chip thoughts here..
i got my abt stage one, supposedly 163hp and 268nm.
feel:
more responsive to throttle response.
sound:
quite a lot noiser, especially at the 2200-3000 levels, rough sorta rusty sound coming from the engine....anybody got this after chipping?
Speed:
raced a WRX and he gave up after i hit about 170kmh, when i stepped on the second stage of our throttle, it kicked down 2 gears i think....CVT
next to come:
bpv, either forge/evo or gfb.( any suggestions? i'm torn)
high flow filter (kn or itg, still deliberating)
0-100 speeds are still not significantly better, on cvt mode posted a hand time 8.8s.
will dyno the car soon and post.
later people....

I get the sound also..
second stage? do you mean the little extra step after pressing down all the way? if so, then the car isnt "downshifting", the CVT i smerely reprogramming itself for maximum power.. remember we dont have "gears" in our cars...

of cos we have gears...just that it's not a preset gear ratio,
the fact that the rev goes up meaning the gear ratio becomes bigger, rite?
im confused....
i only got the stage one, abt dealer here sez safer to go with stage 1 for cvt, abt doesn't really recommend stage 2.
think that after i change the stock bpv it'll improve?

0-100 in 8.8 seconds? That's faster than a 500HP+ Lamborghini Diablo
0-100 in 8.8s? No-way. A good 0-100 time for the 1.8t would be anything under 17 seconds. Stock 0-100 time is about 24 seconds. The A4 3.0 does it in 21 seconds. I doubt that there is any production car that does 0-100 in less than 10 seconds. The dodge viper Competition Coupe does 0-100 in 9.2 seconds. Check your numbers.

no we do not have gears...
we have a chain that expands and contracts to provide a smooth and seemless acceleration.. the "gear ratios" that you have in tip mode may feel like gears, but its just an sudden change in the chain...
