My truck is a 2005 non flex fuel, my stock injectors fit the TBSS fuel rail and intake with no spacers needed.

Stock on left, NNBS on right.





I used the evap solenoid and line from a NNBS truck, everything just plugs in with no modification needed.



I kept this intake because the port for the MAP sensor is broken, this is held in with silicone. The engine harness needed to be taken apart to pull the harness for the MAP sensor out to make it reach.





For the PCV hoses some extra silicone was used from another project.



The TBSS throttle body does not have a coolant line, switched the steam line that joins the heads to the NNBS steam line.

 

For the time being a NNBS intake tube is being used, will eventually install something a little cleaner looking.

 

After the install I went out for a long drive and here is my thoughts.

1, The throttle response does feel quicker.
2. Half throttle torque feels improved.
3. Undecided on WOT improvement.

 

I did mine just before winter and got it tuned during the winter and really havent had much time to play till lately wot is horrible big delay.

 

Do you have the larger throttle body also?

 

I have the 87mm going to upgrade to ls7 it has a better motor it quicker.

 

what heads are you running...5.7 ls1 motor correct?

 

5.7 LS1, rebuilt to LS6 specs, running 243 heads. Considering upgrading from the LS6 cam to something a little more. CNC heads are also on the maybe list. Poor engine only has 2k miles since installing a couple weeks ago and already I want more power!

 

I dont see an x-link in any pics.. Did you just plug in the 87mm tb?

 

what injectors are those?? size wise?
