Has the truck been to the track yet? I bet without nitrous you would run deep 11's... to simplfy things you could run one big stage on a toggle switch. If you have a progressive controller then that's a whole different ball game :D

If your going to run a 2 stage I would run the first before and the second after the intercooler. You want a softer hit on the first stage unless you a well sorted out chassis. Jeff

My first stage(progressive) is Y'd to hit both before and after the intercooler at the same time. Bigger jet before, smaller jet after. Although its microseconds, the smaller jet warms up the the engine for what is coming next. Second stage, if needed, is in the intake, and works off of a button.

You might want to check with Rob on the tune before you spray it(fueling, timing) but what you have will certainly handle it. Start small with the jets, see how she reacts, and work your way up slowly.
