I plan on using the White Racing adapter with the lates Gen 7+ ECU [/qb][/QUOTE]Did it ping with 8* initial? I'm curious as to what your initial timing was at since the computer only commands 24* at 4350rpm with 10* initial. You may have a bad BP sensor which would add 4*-12* timing if broken. [/qb][/QUOTE]JeffS- Yes it pings at 8 degrees initial. I have no codes for a bad BP sensor, however I have a couple spares on the shelf I can try. Thanks for the info. It runs great and this ping only happens in 3rd and 4th, ie heavier loads. Track times, 13.4 @ 110mph with a 2.4 60ft. This was with a wasted posi and 245/50/16 rear tires and a stock RPMII intake. Now I have a 31 spline Eaton posi, 285/35/18 tires and a gasket matched Upper and Lower for the RPMII. Mtbaughs, yes the Dyno operator put in the vehicle weight, he seemed knowledgeable about the dyno. Thanks for the great info so far. [/QB][/QUOTE]
