Alright, I'm not sure I will find anyone who knows, but here goes. I have a 99' 4runner with TRD S/C. I am wanting to add a 7th injector kit to it. I don't want to get raped by the stealership, so I have been searching for a shop that has dealt with the 4runner supercharger directly. This is the same supercharger for the tacoma, its the 3.4L engine. Any help would be greatly appreciated. Thank You In advance.

Are you looking for the kit or someplace to install it? It's really very easy to install, 5 wires I think if that. Tee the fuel line and run to the 7th injector that you bolt to the bung that is already on the SC.
If you are looking for a kit get the one from UnderDog. Its better than the TRD kit and cheaper.

 

I'm wanting to get the kit from URD. But don't know much about piggybacking to the ECU. I wasn't sure how hard the install would be. I tried to get ahold of URD but no one has responded. Even if I do install myself I will want to find a tuning shop that has dealt with this directly so I can get the proper tune done.

 

You're probably not going to find a shop that has worked with it. The unit itself it pretty straightforward though I don't think there is any tuning required just hook it up and go because it is already programmed for the selected vehicle. If you get one of there timing modules then you would probably need to have some tuning done to dial it in.

 

imo it would be easier and safer to just get a set of 6 bigger injectors, then get a s-afc and have someone tune it. it will prolly run better in the long run. just give xat racing a call or post in their forum. i used to work there so just drop my name, they won't do you wrong.


ohh and please upgrade your fuel pump while yoru at it. its realy cheap insurance for your motor.
