    Newbie 04 cobra, pinging problems

    Not sure how soon I can get it back to the shop to adjust the A/F ratio down from 12.5. If I add octane boost or a few gallons of race gas (or anything higher then 91 octane) will that help temporarily richen up the A/F mixture, or will the cpu compensate? Or the shop also gave me a second...

    Newbie 04 cobra, pinging problems

    Yes, did forget to mention that. I originally bolted on a Bassani x-pipe but it wouldnt seal, so had to resort to the H-pipe for the dyno run. Also have a new BBK throttle body I want to bolt on after I have the intake ported to match the tb. So when I get those 2 situated I will be taking it...

    I only took home the chart with the HP and Torque curves (attached), another graph had all 3, the A/F was a solid 12.5 line up to let off around 6k rpm.

    finally tuned! Finally got her tuned today and the pinging is gone for good at WOT. 2.76 BF w/idlers, K&N FIPK, Mac o/r h-pipe, 2 ch/flows catback, with SCT Xcal2 tune. 455/476 on 91 oct. The boost was registering just over 13psi max (lower then I expected), so perhaps the warmer outside...

    warranty Yes, I did get an extended warranty, so shes good for 5yrs or 60k miles. Just got the SCT XCalibrator 2 Tuner and booked time next week to take her in as is, before I go bolting on any other mods.

    no chip I checked for a chip and there wasnt one. I am assuming the previous owner must have removed the chip or program tuner before they sold it to the dealer (or perhaps the dealer did), since even running octane boost didnt resolve the pinging. Thats a very horrific picture!!!! enough...

    Newbie 04 cobra, pinging problems

    Just bought 04 cobra w/ 15k miles and seem to be having pinging problems. The car came with K&N filter, billetflow 2.76 pulley, x-pipe and some quite mufflers. At or near wide open throttle and 3000rpm and up she pings, otherwise normal driving is fine. Initially thought the svt dealer put...
