Cuts out whenever going quickly to wot, any gear or speed but worse in 1st and 2nd. It's got a manual valve body aode with the original auto computer and and sct chipped tuned by Lsxkiller in Kansas. I replaced the distributor, coil and tfi module while it was on the dyno and the problem went away so we thought it was fixed however we got it home and it has come back. Replaced the pip again with a new motorcraft and got one clean pull on the street then it came back again. Would a tm40 5 spd computer do anything for it or does the sct chip wipe out the automatic shift parameters anyway? Any ideas would be great this thing is killing me!!
