Hey guys,

previously, only in normal mode would i hit the revlimiter when accelerating hard off the line, now its started to happen in power mode.

basically im guessing its not changing gears quickly enough, anyone have any ideas?

TT Soarers have an ignition retard/fuel cut that kicks in upon gear changes. Its to help save the massive stresses that turbo's put on clutches inside the box on gear changes. So in effect it sounds like Snap Crackle Pop... But its there for a reason.
When you say " Off the Line" do you mean as soon as the boost kicks in you get a slight miss for a second and then on gearchanges as well?

i meant, standing start, id put foot to the floor, it launches, gets up and bounces off the limiter. previously, in power mode it would not hit the limiter at all

What kind of modifications are you running, and how much boost? Also what kind of spark plugs are you running?

ive got a boost controller, but its still running stock boost. had the spark plugs changed recently, i cant remember the model number but it was stated as bosch gtr or something, so decent quality.

no mods as yet.

It sounds odd it would hit the limiter. I don't normally hear the flutter on full throttle gear shifts but I don't hit the limiter either and I've done quite a few runs at the drags this year. Only time I hit the limiter is in the burnouts when shes spinning the tyres :-)

I had the EXACT same symptom with my gearbox before it f**ked itself.

Check your tranny fluid. If its brown/smelly/not ruby red have it changed. See what happens.
