2008 gt manual with hurst shifter, after the centri supercharger installed, i feel the car acceletate extreme slow in 1st gear, it makes me feel the car is very heavy,(accelerate feel not like 2011 gt or normal 5 speed manual), and very hard shift to 2nd gear, after that, no more problem. is it shifter problem, tranny problem or clutch slippery? i kind of toward its the clutch problem, because the car moving very slow even i lift over 1/2 clutch without apply throttle on a flat ground.

English is your friend, learn to type better.

You most likely have an issue with tuning. Find a competant speed shop and consult them.

There, I corrected your post in bold.

My guess is a glazed clutch?

simply because it best to consider the simplest things first, have you checked to make sure its not your traction control kicking in (spinning the tires). when my tires break lose alot of the time its dead silent. i dont' even hear it.

only way i know is if i was turning and the rear trys to kick out, or because the car bogs down from traction control kicking in.

its happened to me a few times( i wasn't even trying to accelerate fast, just barely going) car bogged down leaving me going wth? happen to glance down and sure enough my traction control indicator is lit up.

and this is on my stock gt, considering you have some nice power adders id say it would be even more likely for you

Try re-calibrating the gas pedal. It does tend to get out of calibration from time to time and this certainly effects take-off! A couple of times I have sensed something was not right and after re-calibration it was like a breath of fresh air! :-)
