Car shuddering

Any one know what's wrong with my car? When I'm driving my cay and it's shifting into 2nd and 3rd gear the car sort of shudders as it's going into the higher gear. I was thinking that maybe either the transmission is giong out or maybe a motor mount is bad? There are no indicator lights on, engine vsa or otherwise. Or maybe just loosing traction? As this is only happening when I'm shifting at the redline. I just put in a really good fuel map into the E-manage, so it might be because of that.

While at a stop.. put your foot on the brake... then apply the throttle....

report back if you feel the shudder... it means you got a bad mount...

I lose major traction between 2nd and 3rd while shifting at redline... I know the feeling... @ first I thought my clutch was shot.. but I was spinning those 18 inch rubber bands all the way down the street...


I did a test last night.... I heated the tires up.. then made a quick run.... the tires grabbed this time around and almost pulled the car off the road in 2nd and into 3rd gear.

Yeah my friend was saying he thought I was loosing traction, but into 3rd? I'll try the brake thingy. As far as the map goes, this is probably the best the cars run yet so I'm gonna leave it, it's running really good, the throttle feels real crisp.

Oh and the supercharged motor feels totally different with the manual transmission. The gears are so much shorter you are always above 5500 rpm. Yet in daily driving you can keep the revs below 3,000 and still have plenty of torque to make your way through traffic
