Been doing alot of looking for why my car has no power.. Got the car in march with a bad trans decided to go ahead and do a lil work to the motor so i put stage 2.5 prc heads ms4 camshaft ls6 intake stock bottom kooks long tubes and 373 gears all new gaskets and sensors sent pcm to tsp got a mail tune had bad problems for the first few weeks found out the new factory maf was bad it helped with the lean codes but the car still feels very slow changed all the plugs wires coils twice no change trans was rebuild completely with shift kit and power pack i did go with a dacco stall... very bad choice putting a yank ss 4000 in next week. The car feels like it has a miss or dead spot about 50% throttle around 3k to 4k rpm fuel trims and o2z dont show a miss or dead cylinder im still lost at the problem after months

You have any way of scanning the tune profile?

All i have is a bluepoint scan tool no way to view the actual tune

Car defiantly needs a tune!! Every tuner can't make a huge MS4 cam idle or run like it suppose to... the big cams can be tricky to tune basically.

Ill try to find a good tuner after my stall swap just wanted to check with others input first cash getting tight after the stall

Get the car to a shop that can scan the car to look for possible problems, preferably a shop that deals with LS cars on a regular basis. It might be as simple as a little bit of tweaking on the tune to get things acting right.

You really shouldn't do Wide Open Pulls on a mail order tune.
You could have potentially damaged it.
Who knows if the car is lean, detonating, knocking or needs timing pulled.

Also I bet 1/2 of your problems is that you are using the stock stall.
The MS4 is going to really hate your stock stall.

Without a stall to compliment your cam, you will show no noticeable gain at the track.
