well I gotta agree with Tim here. a fuel pump thats blowing fuses could easily be causing lean conditions if its flaky.
and a tune is only as good as the rest of the system. and if the system changes out the door, then you can have these issues.
I remember trying to tune my AAR years ago after installing a BG Fuel pump and regulator. The regulator would vary its settings almost constantly. sometimes fat. sometimes lean as hell cause the fuel pressure was changing. I remember having to adjust and readjust that puppy several times before I realized it was just a POS and wouldnt hold a setting. Within a few months of trying it, I blew the tops off my pistons (detonation caused by a lean condition).
I can see your all trying to hang DCX here and its not necessarily the right place to point your finger yet. When you modify a car for high performance and then run it hard, THERE IS RISK YOULL TOAST YOUR MOTOR.
like my dad always said, if you want to be Johnny Race Car Driver, get ready to spend some money, and replace some broken parts

and thats another thing, when you mess with a car, you better sure and hell be datalogging parameters to make sure everything is working right. if youre running down the track at WOT and your pinging that beotch, I can guarantee youre going to lose a piston.
