Ok, here is the story.. I have a 2007 A6 vert, mods are AR headers, stage 2 patriot heads with a 59 cc chamber, and a 2006 ls7 cam. have it pretty much ironed out,, but I am having a prob during shifts. I cannot get rid of a bad detonaton BETWEEN SHIFTS... If I hold the gear it is fine 1,2,3 all ok.. But when I shift the car or it shifts itself, It has a bad rattle and the Knock sensor comes on,, I have tried adjusting the timing at the rpm drop point and still nothing,, It ONLY pings during the actual shift. The plugs are 103's. ANY HELP PLEASE... I am located in the STL...

The car is running its *** off, but I need to fix this detonation prob

O and I have turned the fuel up to the point of it dropping into the low twelves high 11 ar right at 6500 or so right before the shift to try and quell the prob,, still no go.. rest of the fuel curve is right in the high 12's low 13's I fattened it up to try and help,, but,,,,,,,,,AAAARRRRRRGGGG

 

Not sure were SLT is but if you can get hooked up with Chuck from COW I am sure that he can help you. He can also trick out the auto trans! Just one option.

Good luck

 

come on guy's I need a little help here,, somebody MUST have run into this while messing with one of these........
