    In reference to the edelbrock 454 tbi intake, even though they say it won't fit 91-95 it fits just fine. There is a couple of assessory holes that are different but it works just fine. I have it on...

    Have you got setup yet to do proper data logs. It could be that it is rich enough on start up but as temp increases and it relies more on the ve table in open loop and the ve table is not correct.

    My opinion would be to switch to computer that came with that setup. Would probably have been 7427 running $OE or $31. If you can't find a harness you could probably modify your original. I think...

    If you want to use $OE use the xdf and adx that you find under the 6395 computer. 6395 and 7427 are interchangeable. You would need to use a $OE bin
