Here are some questions about these vehicles I have.

1. Do you think a '03 Cobra will take 125-150 hp shot of nitrous if properly tuned? As you are surely aware the new Cobra has all forged inerds and an iron block. The trans is the Tremec T-56 six-speed.
2. Can you explain power shifting during a drag race?
3. What would cause an engine to hesitate while trying to accelerate while in load conditions? The truck (supercharged 99 F150) feels like she is missing. I changed to NGK plugs one step cooler but that didn't help either and gapped at .035. My EGT is about 1000degrees at 2000rpm. The hesitation comes on just as the boost guage reaches the 0 and lasts till 3 psi. It goes away above that. Fuel pressure is about 47-50psi during this load condition (has a boost adjusting FMU 4:1).
