I can feel your pain as mine does the same thing! It idles perfect in the drive way but the moment you close the hood it changes and does the exact same thing as yours at stops! It was suggested to drill some large round holes to allow more air in but this really kills the look. At speed it's fine BUT I read a thread somewhere that the turkey pan really kills off some HP! I'm ready to sh-t can it myself but it looks so damn cool, plus all the work that went into it to make it work. I don't believe I have any vacuum leaks either. I'm about to try a double pumper to see if that helps wake the motor up any. Let me know what happens! Matt

I have no problems with my TP and Holley 750cfm combo -- it idles fine, runs great, but I'm a believer in smaller carbs, rather than larger. If you remove your air cleaner entirely and close your hood do you still have the same problem? BTW, the studies and comparisons showed that it was not the TP that caused the reduction in HP, but rather the air cleaner that was used to fit inside the TP. If you use the K&N air filter with the S&H housing the HP reduction is not very much (there was still some, if I recall correctly, but it wasn't enough to matter).
