Did you have this is due since day 1 of it getting tune? Have you driven the car since the throttle adjustment? My first assumption was also that it's a tune issue. How much psi? 7? 416 is pretty weak for a 4v. Sounds like the rest of the car is completely stock?

No it is something that has pretty just started to develop. I just had it done today. There is nothing wrong with the tune. Yes the rest of the car is stock. Remember 01 cobras did not have the internals as the 03-04 cobras. Those are the years Ford put in better internals. The 01 can handle right 450. I think by the time I am done I should be close to 450. I am running 8 psi. I have thought about changing the pulley just not to sure. I do not want to spend the thousands of dollars right and build it over time to my liking.

I'm making 508rwhp through an auto on my stock motor Mach with a Vortech at 11.6psi. Well aware of all the different internals.

If I change the pulley I think the hp would jump up there. I would love to change all the internals and max out the hp on the stock block. Right now I am just going to do what I can before I spend the money on a full engine build. If you have any suggestions on more power I would like to hear them.

More boost. Nothing else is really going to give you a significant bump. 10psi should put you in the 450-460 range.

That's the next size up from what I am running now. I just have to contact procharger and find out how much that will cost. Thanks for the input.
