good luck, nice numbers.. BTW... M6/A4?

i am dropping the car back off on monday. hey Brad why is a 110 harder to tune?
I am going to tell him to set it at 850-900

ahh i see. yea i want that idle lower. The decater rate the guy was playing with. That is messed up a bit. when you take the car outta car caosting it revs to 2k and sits there till you put it back in gear or come to a stop. he said that it might be bc my battery was dead when tuinnging f he changed one table another table was affected..
But agian yea i want to lower the idle

Glad you went with the 110LSA +4 cam. See, you can actually get solid advice on this board! Congrats on the big power gains!

Yep thanks Patrick for the advice...
The only problems that i am having is that at 1400 - 1600 RPMs it bucks
and 4th at 2000 and 5th at 2000 RPMs the car hesitates for a second when you give it 1/2 - 3/4 throttle...
And the idle is set at 950. i wish that it would lope a bit more. The tuner tried to lower the idle but cold/hot starts were rough..
Got any ideas?? Thanks again

The cam you're running is actually not that big. The problems you're experiencing are totally tune related. First thing you have to do is set your base idle timing right (probably 22 degrees). Then, set your idle speed to 850rpm. Next, see to it that your IAC counts are between 30-50 at warm idle with ac off. After that, set your base running airflow to where your short term idle trims are closer to 0. Most likely, you'll need to reduce airflow. Once your airflow is set, you can begin VE tuning. I'm pretty sure your A/F ratio is all over the place at those lower revs, but 80% of the bucking and surging problems are related to running airflow being off. Get the airflow right, then to a good VE tune, rescale your MAF (if you're using one) and you should be a lot closer. FWIW, you can make a T-Rex have good street manners with the right tune, but without it, it's a MF to daily drive.

When you say the problems that i am experiencing, the bucking and hesitation.. Those are tune related???? Man this sux.. The car has already been out there 2 times... what other advice do you have more for that i can tell the tuner??????
This is fvcking annoying....

Most tuners can't stay in business spending the time to do a proper drivability tune. It takes hours of logging to do it right. But the majority of your problems are definitely tune related and fixable. Lots of great advice in the PCM section of this board.

Ok... I will have to talk to my tuner again see what he says.. i do not want to stick with a poor tune if it can be done right....
If i have any other questions i will PM you.... I hope that they can be fixed and that the tuner will cooperate with me......
Thanks again Patrick!!!
