do you recommend a tc with an sc or will it hit the rev limiter. I'm about to install both or maybe just sc if it is better without the tc. Any suggestions welcome.

 

What car do you have and what other mods have you made to the vehicle?

 

Gears (like 3.76 Supra gears typically with the torsen LSD) cause it more than a TC will.

I hit the rev limiter with mine regardless, but changed the stall speed to 2600 I think (instread of normal PI TC 2800) and ordered one with a 'turbo stator pump' and it helped significantly

 

its a gs430 no engine mods other than k&N filter and exhaust. But I am about to install an sc and tc. I waqs just trying to figure out if there was any problem with installing both.

 

On the TC with a GS430 do some digging first... many GS430 owners who installed them got a check engine light CEL that they cannot resolve. May cause problems with your inspection.
