I cancled my order with LFP and called Rick at Amazon for all mods and install with a custom Dyno tune. My app. at Amazon is Wed. the 3rd at 1:30 if any other cobra onwers are close come buy so i could get some ideas for later mods. What kind of numbers should i get with (2.9 RR upper, 4lb lower, MAFIA, Aux Idler,Plugs,non cat maggy x, Maggy cat back, K&n CAI, and Rick's dyno tune) ? I hope to see some of you on Wednesday. Later, Rob
