So when you're under full boost, does the car bog/lag in between shifts? When going balls to the wall, my car will "hiccup" as it shifts. I'm assuming this is b/c of the increased power. Will a valve body upgrade get rid of this or a new torque converter?

a valve body will help cure that with the faster, harder shifts.

I would get the GTM or SGP VB (I don't think forged sells them anymore right now). I have the stillen and it's perfect if you are n/a or below 350hp/tq, but once you go higher than that it pauses to shift and you will hit the RL even if you shift at 6400 in MM.

A TC will help handle all the extra tq. I got mine from edge racing for $400-$450 they just modify your TC to what you want. Ask for Andre if you go that route.

^^his car shifts smooth as a mutha!!

I don't think you have a trans issue - it almost soudns like a tuning issue. Alomost like the car is too advanced during shift - not tuned right.

Have you had the car tuned? what EMU do you have?

Most likely bro you just need to get the VB and TQ... after getting mine tuned at SGP my shifts are the same way... after the summer i am going to got back to Mark at SGP and have them do the VB and TQ... i am also going to go with a bigger tranny cooler...
