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

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.

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

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!
