I was running 1 stage colder plugs. The NGK 4306's I believe was the plug. As for my mods. I'm running TorqStorm SC on 7lbs of boost with a custom intercooler setup. I also have a Crazy Jay Plus cam which is not a boost cam. I had the cam installed before I ever thought I was going to do a SC. I've also got longtube headers into a custom 3" dual exhaust (with no crossover), 87mm ported TB, 3.92 DTT rear. Tuned by AJ aka HemiTuner. I still have the stock trans and converter on the truck, though I do have a 3000 stall Edge converter sitting in the house. I also have a AEM high flow fuel pump instead of the stock pump.
Completely stock my truck ran a best of 15.3 the one day I took it to the track. Haven't been to the track since though.
When AJ tuned it the best numbers we got were 407hp and 400tq to the wheels. (I'll also mention I'm running 22" SRT 10 wheels so that could have effected the numbers, though AJ was very pleased with them).
And just to clarify what Steerman said, I haven't traded in the truck but it is for sale. I went out and got an 04 RC SRT 10 Ram. I couldn't help myself lol
