SI and Veloce do not offer TCU upgrades. You do need the TCU upgrade for faster shifting and to maximize the results of the ECU upgrade.

This group has a good rep and Aaron with StealthAuto sells their services. I highly recommend them.

The TCU upgrade is almost as important as the ECU upgrade. I went with AdamG for my upgrades and I couldn't be happier with the results.

So, when I did my ECU/TCU, about a year ago, was that Evotech's software through Renntech? If so, I'd go with Evotech because I was very impressed with the results. Not to mention, I'd imagine there is a significant price difference between the Renntech and Evotech upgrade.
The TCU is important because it makes the tranny much more responsive and behave more like a manual tranny. It will hold the gear longer when you are driving aggressively and will downshift quicker. I noticed a big difference over the stock tranny with the TCU upgrade.

Thank you Jim...
Renntech is selling for $6400 and Evotech for $2595. Personally, I think its a steal considering many tuners don't have a TCU upgrade to accompany its ECU upgrade. And we even have a 7 day money back guarantee!!!!!
