throttle body won't open all the way I got an ls6 intake and a ported and polished 85 mm tb, after install the blade won't touch the bump stop. There's about a 1/2 in space between the blade and the bump stop. And the throttle cables has been adjusted (tsc car ) . Any Idea how to fix? I need to get it fixed by Friday for the races.

Will it go WOT by hand without the cable attached? If it will and it is a cable placement issue. All you can do is adjust the cables or notch the bolt hole in the bracket and slide the bracket back.

Yeah I can open it all the way, we adjusted the cable and there's still slack. And you're talked about the brack on tip of the intake?
You may have to bend the arm on the gas pedal to
get enough cable draw. I did, and on another local
dude's car he couldn't get past 85% TPS until we
did it to his. With everything adjustable, adjusted.
You could do the same with spacers too, but it's
two bolts, two minutes and a piece of pipe in the
bench vise.
Now I also ran into the TCS "gizmo" limiting the draw
when I swapped up to a 85mm TB, and at that point
the throttle & cruise cables I swapped to non-TCS to
bypass that mess.

Verdad Gallardo ya thats normal and a good hp gain for the money you can actually file down the bump stop to get the blade to open full as its only open about 90% whenit hits the factory bumpstop. anyway with that said you should have no issue with adjusting that tention. have you adjusted both cables leading to and from the tcs box
