Start up before tune stumble. Normal or not?

[QUOTE="VA-Mach1, post: 16350053, member: 161447"] Installed a Vortech V3 Si on my 99 GT. Started the car and everything is good until 1500 RPM when the motor starts to stumble as if missing when gradually applying throttle. It does not clear up with more throttle. It will stall out if I give it more throttle. If I blip the throttle it will quickly go to 2000 or 2500 RPM and drop back down as normal. I don't want to push it to much before a tune. Just wondering if this is normal before a tune. Did a Google search but didn't come up with much. I'm in the process of scheduling a dyno tune now. Any input from experience would be welcome. Thanks Setup is: Vortech V3 BBK 78mm Throttle Intake CXRacing Air to Air Intercooler W/Bypass Valve piped back into intake before supercharger Ford Lightning 42LB Injectors OEM Ford Ford Lightning 90mm MAF OEM Ford before supercharger DeatschWerks In-Tank Fuel Pump 340 LPH NGK TR6 @ .030 [/QUOTE]
