well i have the hypertech programmer. it allows me to change the shift pionts by up to 500 RPM, and increases shift firmness(very little). i know there is like rebuild/shift kits. are they worth the time and moeny, because the electronic tuner is doin very little for performance besides letting me rev out first and secound an extra 4 and 300 RPMs. BIG-WHOOP!!!!

Do the mechanical mods, tuners and programmers just bump line pressure which isn't good at all.
I did the Sonnex valve and Tricummulator Springs in my '99 V10 and the shifts were great. I hope you like the shifting of a sports car cause that is what youa re going to feel like you are driving.
