I have a 100 shot direct port. Internals are stock, fuel system is stock. A bunch of people have said u can go to 150 on stock fuel because the kit automatically adds sufficient enrichment fuel, I don't believe it, so i just stuck with 100. Might try 125 sometime but still not sure. The best time is a 12.63 in a pretty strong headwind. The other mods i have are O/Rx, flowmasters, pulleys, centerforce DFX, drag radials, weld in subframe connectors, cold air, throttle body, lowering springs, line lock. I'm probably forgetting something. It still has the stock gear
That will change this season.
