Tune and exhaust note?

[08DarkCandyGT]

Guys i first got a no tune S&B intake. Car ran ok not to much different. Then i got an SCT X3 and used the 93 canned tune. Could not find my intake on the list and picked K&N since they were both no tune. Cars exhaust got much louder on throttle and it had good low end power. Then got a Brenspeed tune. 93 Perf. Car woke up with good throttle response but more power after 3K.
The thing is the exhaust note really mellowed out and the low end power seemed to be gone. What is the reasoning for all this? Anyone know?

Canned tunes are hit or miss sometimes. call them and describe to them what is happening and they will make adjustments. This is what I have heard, not first hand experience here.

Breenspeed has great customer service....if you have any problems e-mail them or call them and they usually get back to you within a day. I called them this past year because I failed emmissions (my tune from the turned off the o2's) and I got a response within an hour.

Also, my 93 tune is kind of the same way. A little calm below 3k but it wakes up big time after that. I have been told by several users of Breenspeed that their 91 is better down low, but worse up top. I guess it all depends on what you like. The 87 tune blows so dont even bother using it ...not much better than the lame stock tune
