Hello i have a 99 gmc k 3500 with a vortech 7400 454 it was having leak down issues and it was about time for gaskets.
So here is what i changed
New intake manifold gasket felpro
New plenum gasket felpro
8 new bosch 0280155884 19 lbs/hr 196 cc/min High Impedance injectors
New cap and roter ac delco
New oil switch gm original
New fuel pressure regulator ac delco
Took about 5 hours and got it done boom solved the leak down issue however now my truck is running super rich and at idle will surge just a tad. ( also has a really low idle)
Question is how and where do i go to get my black box pcm re tuned and bosch and 50 motorsports Both said they were direct no tune needed injectors.
Im stuck and really want to drive my truck again
Thank you for your time
