Is your problem while driving? or at idle? or both? Have you called HSP to see if they have suggestions?

It ran great before your addition of the HSP bundle, now it doesn't. Something not done correctly. Double check the MAF and MAP sensor installs and wiring, If you have a capable tool, Read the MAF at idle. Should be about 37 gm/sec +-.
