And you have an SCT?? Can you monitor fuel trims?? It may be a fuel delivery issue I would datalog it and send it to whoever sent you that tune.

This is the stock tune. Stock tune shouldnt do that right?

It also does it on the AM email tunes I have.. along with the pinging which is why I run the stock tune for now till I need a dyno tune.

Got a chance to take the mechanic who did the prior work on the car for a test drive, seemed like a nice guy, said he worked at Ford dealer prior to this Chevy dealership, and owns 4 mustangs, one he said is "modified alot"..

Anyway, the rpms stalling out at 4k he said he couldnt reproduce when he drove it, but he saw it when I was driving and suggested having the cluster serviced/replaced his reason was that the mph is still climbing so maybe the tach in the cluster itself is bad, so I asked "well why doesnt it do it in 1st gear?" and he said the computer is recieving differant signal or something and so is sending differant one to the cluster kinda sounded like a wild guess to me(I have 3 ase certs.).. but since he sees it, if the new cluster doesnt fix it, they now cant deny that there is an issue is the way I am looking at it.

He also heard the front end creaking, I tried to tell him I thought it was str. rack bushings(if you get down on ground in front of car and have someone crank the whell back and forth its pretty obvious its the str. rack or the str. rack bushings), and he sorta agreed, but also recommended replacing something "struts" and "upper and lower" I am unsure what parts he was talking about exactly. I forgot to mention the tsb.

I told him the codes could be a vacuum leak, and he said he would expect it to idle badly if it were vacuum leaks.

Car is going back to dealer on Tues. next week. Will have about 800-1k miles left on warranty at that time probably.

Any more help very much appreciated with this.
