I currently have a 3.4L 2000 4runner supercharged with the 7th injector, (I understand that URD offers better fuel mods). The whole reason I went with the 7th injector was because it seemed to be a plug n play, never need to touch it again type deal. However, I am noticing a dramatic power loss after the car warms up and the fan shuts off, (about a minute after start up). It kicks you in the pants right after start up, (doesn't matter if the engine is warm or not, the power is there along with the whine)... but soon after the fan shuts down it feels little better than stock, and of course the whine diminishes significantly, (no boost gauge). I am certain some of you gurus have seen this before. I tried a search... but had no luck with that. :pat:

Perhaps it's time to go with the URD supergrip 9 lb pulley, SAFC, colder plugs, supra injectors and walboro fuel pump... knew I should have done this the first time around.

 

URD has a kit to complete the TRD 7th injector, shouldn't need any bigger injectors. http://www.urdusa.com/product_info.p...s_id=110000039
