Hi Nuke
Sorry I forgot to tell you about torque gain 13-17 Nm then stage 1.
Actually we can make it more tq but we concerned durability and fuel consumption.

Great and one more thing as people been asking in other threads about the throttle limitation on 3000-4000 RPM and if your TTi's tune removes it

Hi Nuke
We have long-term test in the recorded throttle opening degree and pedal angle of the two sides for compare.
Basically the stock throttle reaction is slow then pedal ,that is the pedal and the throttle do not move at the same time even 3000-4000 rpm(will be arise every RPM range), We adjust this parameter to synchronize the two sides.
There are something products selling in the market and make you throttle fast ,Finally you can not avoid the reverse correction by stock ECU program as same as like Lambda control.
Sorry my english very poor
I'll do my best to let you know what I mean.

Thanks Tony, but am not talking about throttle response but rather am talking about Throttle limiting, see the post below by MasonGrey

This graph clearly shows that there is a strong throttle limitation between 3000-4000 RPM and we are concerned if your tune is addressing this issue or not

Hi Nuke
We have been in the test of the stock horsepower has been found this problem, you can look at the dyno graph green circle before and tuned result.
Whether someone else has improved this problem is not important, and now we have improved it.

FYI
Thanks for clarifying Tony, this answers alot of questions of many people who are curious about TTi's tune.
