I just had my engine rebuilt and this cam installed
(sorry the image is huge)
I had the ECM tuned at Nelson Performance but they said they didn't have the software to do a "livetune" on an OBS so it was just a mail order type tune.
At first it was hard to start and idled really rough like it hadn't even been tuned, they tapped out the little hole in the Throttle Body to allow more air through and that helped it idle a little better.
It still sounds like it might stall out when if first starts but then smooths out pretty good once it gets going, sometimes it won't start with the remote start anymore on the first try, the second time it will have to crank several times before firing off. They said it might take a while for the computer to adjust itself, it's been a couple weeks, 15-20 short trips and at least 200 miles.
Is this how it's supposed to run with the cam or should I take it back to Nelson or the mechanic? The motor has less than 400 miles on a fresh rebuild with the new cam. What do you guys think?
