auto tc question

[noobsciondriver]

hey there ppl well...i have an auto tc...and i was wondering if there is any way to improve its speed other than the trd s/c...i know that it still wont compare to the manual tc but does anyone have any suggestions?

you can ask anyone here...they will probably just say intake exhaust and headers

ZPI has a full auto upgrade that make that useless auto come alive. Alot of R&D was put into this. As far as I know, no one even has a shift kit for it.

My first oil change seemed to make the biggest seat of the pants improvement on my auto. I got the TRD exhaust which did a little more and I have the K&N drop in air filter , removed the charcoal air filter and added an additional suck tube to the stock airbox which added a bit more throttle response feel.

Should have saved the money for a true CAI. You would have gotten more performance and better looks. The TRD Exhaust is IMHO the best out there for the stock tC. As you know it provides a deep, mellow tone that is not too loud or harsh. Take away the stock header and bam! Instant noise and rasp. You won't like it. You will have to add a large performance resonator on the mid-pipe to cure the rasp.
