It's throwing a code for the MAP sensor and running like **** so im taking it back tomorrow..... I wish it would just work fine; haha. It's almost died on my like twice, once it did. When I push in the clutch and stop at a stoplight the RPM's are all over the place.
Sounds tune related eh?

I work for valley center fire...... small world
and btw, I picked it up again. He said the light went on right after he started it up. He Talked to a couple other tuners that have done V's and a few of them said that my car needs to learn the new cam. He said just drive it around. I picked it up and it was way better than before. No engine light either this time. He didnt do anything to it except just test drive it and see what it was doing

Yeah car is tuned the tuner wants to see it to try to diagnose just haven't had time. The check engine light only comes at idel once I start driving it goes away.

I was under the impression that after tuning the car, that eliminates any "learning" the car has to do. I had my car tuned by Cunningham Motorpsorts in Temecula after I did my cam and had no issues. Drivability was spot on, no CEL, etc. If you continue to have issues, it might be worth getting the tune checked by a second opinion.

Took it in for that second opinion. Luckily the code was on when I got there. Says something about the MAP sensor and bank 1 and 2 running lean. The guy did a quick check with some spray to check for vacuum leaks and found nothing.
Im thinking it might be the MAP sensor going bad. I hope. It runs wonderfully when the code isnt on

Especially for idle, Base Running Airflow tables for measured airflow affects idle huge... there are limits set as well, usually +- 3g/sec, if you max this out, then the car goes to pulling timing to bring idle up or down to commanded idle. having the computer learn is usually too late in idle conditions.
And you have to remember, STITs take time to respond, idle must be dialed in otherwise, your ECM is hunting everytime you start it... also with throttle cracker and follower (when you let off the pedal to slow down for example).
Cam swaps = crap idle is simply exposing the crappy or inexperienced tuners.
another true test if the ECM has been properly calibrated for the cam is to un-plug the battery for some time... then check how it cold starts / warms up/ eventually to CL.

Thrown CEL could be due to stalling and falling off MAP set thresholds, but doesn't necessarily mean the MAP sensor is bad.
What are the codes? Would be better to see the hpt and log files in this case...(or whichever means was tuned in)
