My car has started running bad up top. It doesn't pull past 4900 rpms or so and once it gets to 4500 rpm or so it starts cutting out. It runs extremely rich now and has started wanting to die when put in gear. It idles fine in park ad neutral and runs well with the exception of wide open throttle in the upper rpm range.

396 stroker
le3 heads
le3 intake
cc306 cam
longtubes
th400 trans

car was a 6 speed originally.

It has been dynotuned before and showed none of these problems.

Here are some log files from lt1 edit. Any help would be appreciated.

Thanks

What size are the injectors? Have you checked the fuel pressure at WOT?

You need to save the files as .csv or in an Excel format. .txt is a PITA to work with.

 

Have not checked pressure yet, will try to do tonight.

Does anything seem odd in the log file?

Thanks

 

Its just too hard to scroll through it as a text file. As I noted, you need to produce a .csv or Excel file, so it can be rearranged and manipulated with Excel.

You didn't answer the question about the injector size.
