I'm a new member and new owner of a 2011 GT. The factory tune seems to have a hesitation or "flat spot" right after the 1-2 and 2-3 shifts when driving normally. Another annoyance, is that unless I stomp the gas, the trans doesn't downshift as fast as I'd like it to and lugs the engine.
I'm definitely a hands on guy. Do you recommend a $500.00 dyno tune or a re-usable $370.00 self tune with a flash tuner.
If the answer is a flash tuner, then which one do you recommend? Some come with standard tunes, and a few come with standard tunes plus one custom tune. Is the custom tune worth it? Will my issues be solved with any of these?
Add me to the list. Although I have a MT82, the tune significantly "wakes" the lower rpm issues, especially throttle response. It pulls a lot harder through out the rpm range. I am running Steeda's 93 octane tune and could not be happier. From what all I can gather a custom tune really enhances the transmission shifting strategy. Just like the above posts, do not use the canned SCT tune. Plug and play 30-40 RWHP is nothing to sneeze at. Torque goes up about the same.
