1) The stock tiptronic is rated at about 319 lbs. of torque, by ZF. Horsepower isn't a concern, but torque is.

2) Most "chip" upgrades produce more torque than this. A couple of tuners do have detuned chips for tiptronics. I believe both MTM and OC.T do.

(Edit: AMS and Abt apparently have detuned chips as well.)

3) Plenty of people run chips that are not "detuned" without problems. My '01 Tip has more than 20,000 APR Stage II miles on it, with no problems. Some folks have even gone to Stage II+ on the stock box.

4) You can get a GIAC "Tip Chip" in addition to any engine chip. While it doesn't technically increase torque ratings, it does increase shift speed, and is "easier" on the tranmission.

5) If you want to go all out, you can send your Transmission to Level10 in New Jersey. They will upgrade the internals such that it will take 700-800 lbs. of torque. It's pricey though. (I bought a used 'Tip box for $2600 and sent it to Level10 to have this work performed. When I get it back, I will be swapping out my stock 'Tip, doing a Stage III upgrade, and selling the stock gearbox to someone who is similarly inclined and equally stupid.)

Good luck!
