Car is a 99 ss, t rex cam, milled .30 98 806 heads, fast 90 intake and tpis tb, mid length headers, true duals. No spray or nuthin, and all motor. All kinds of suspension stuff but we wont get in to that it dont matter on this question. The car was supposly tuned on the dyno at rpm or sumthin like that in dallas texas. The pe modifier on rpm is set to .71 then .72 the after 4800 or so .73. Thats around 10.3 to 10.5 or so afr. That seems a bit rich to me. I would think it needs to be around .87 or so around 12.8 not 2 points off down to 10.5. Someone kno why these guys would do that it really dont smoke when u get on it. But if anyone has anything let me know. I got a wideband to check it but just havnt had time to mess with it. Thanks

Put the wideband in and check it just because you command X doesn't mean that is what you will get. If it doesn't match what is commanded then it needs to be tuned properly.
