don't you use Tracy? I though about getting a hold on him......

 

give up on the tuner and take it somewhere else just my .02

 

please tell me your not talking about Tracy at CincySpeed....

i had some issues with my car, and took it back to him tiwce after i fixed them, and it still didnt run right. it was running so rich it looked like a diesel going down the road...

 

maybe try a mail order tune from TSP and then let the tuner iron out the minor things...atleast TSP can get it on the right page for you.

 

Its all in the tune my car drive stock almost. I get a little surge when i pull to a red light for a bout 2 seconds and then it finds its idle. No probs on cold start or with a/c on

 

my cam is bigger than the ms3 and i put 38lb bosch which is around 42 to 43 on ls1 and am running at 72% duty cycle. injectors could be a little big but its all in the tune. trex cams are some of the harder ones to tune but other than the lope and how loud it is i could daily drive it no problem. the only surge i get is after lockup for about 5 mph over lockup, after that its done. spent about 2 hours on the road on a speed density tune stopping and tuning way more than driving. spent more time on idle than driving. lol

 

Why not adjust lock up to engage after that MPH then?

 

thanks guys. going to take it back till its right...... they have offered to swap out inj to 42lbs, but not sure if it will make a difference or not.

 

Im in Rochester NY I have tuned a couple ms3 cammed cars that all drive exceptionally well. What is it exactly that you are concerned with?

 

bucks and surges when I let out of the gas when its below 1800. the throttle response below 1800 isn't good, it hesitates. thats pretty much it. anything above 2k is fine. and the car runs strong.... just gets anoying with the little things.

 

Oh wow, if its SD tuned, driveability should be very close to stock driveability. Thats the main purpose of that style tuning, to tame any big cam like its a small cam and not rely on a MAF. Having said that, SD tuning is more challenging to do because your no longer working with a MAF. The MAF is what causes most big cams to buck and surge because sometimes it has a hard time adjusting to the overlap.

After a proper SD tune there should be no surging, bucking or idle issues. It should be smooth as a stock cam.

 

normally thats a good idea, but if he doesnt know how to SD tune properly, it may not be a good idea.

 

well I am assuming he does. been doing it a very long time... we'll see give him one more chance and will be going elsewhere.

 

We only tuned once so I'll be going back for minor touchups as soon as I get my trans back in. It'll all be good but that's the only issue.

 

Shoot me a Pm If you want some of my help.

 

SD tunes are over-rated, and not really needed with a setup like this. I think folks go to that well too early too often. I've got an MS4 in my car and it runs like a top, with the MAF in place.

...but without a LOT more information, it would be hard for anyone here to tell you what may be happening. Scanner log files is always a great start.

Your injectors may be calibrated wrong, but that would be showing up all over the log files assuming your tuner is using them to make tweaks on the tune. Fell free to deop me a PM if you could use any help.

 

Speed inc tuned my ms3 car, only took him 1 hour to get it right after they did a mail order break in tune for it. Car drove like stock, is your car a 6 speed or auto? Let me know if I can help with sending you a hp tuners file to your tuner to start with!

 

its a 6 speed. thanks for the info guys.
