Here at the Boost Lab we can also service your GM Vortec "Spider" fuel injectors. We had a chance to document a before/after of our services this morning.

The pictured injectors had a faulty fuel pressure regulator which is why I have a line running back into my flow bench.

 

Thanks for taking care of the injectors. The truck regain its power.

 

NP, Good to hear!
