Is this the 'hiccup' I see referred to?

I have a Eurocharged tune on my stage 3 modded 2006 55 with bigger TB. I did not notice this initially but now that I use manual mode all the time on the transmission I get a stumble when under light load and during the 1-2 shift. I can replicate it by lightly increasing the speed in 1st gear. When it reaches 3,500 rpm I get the same stumble. It just falls on its face before recovering quickly. Is this the 'hiccup' I see referred to and blamed on the bigger TB? There are no problems on moderate to hard acceleration. It is taking the fun out of normal driving. There are no issues if left in DRIVE. Cheers.

No this is something different. I'm assuming you have the 77mm clutched pulley with EC tune?

Yeah I had that issue as well until I switched to an Anthony Lawshee tune.

Same. Lawshee straightened mine right out. I too have the 77mm clutched pulley.

I had the same stumble when I was stock. Got a pulley and tune by Tony and it is gone. It may appear on the first shift when it's cold and the car is cold. IMO it feels like it chokes and then the sc cluch engages then shifts.
