Issues of consistency

[no-tel-in]

Ok, my truck has been acting funny lately, everything is running good but power has varied. When I first installed my tunes a year and a half ago with nothing on the truck but gauges exhaust and intake it would hit 30-32 psi everytime I would nail it. Now I lost about 3-4 psi on the top end with the addition of WW and total ebv delete. Currently with all my mods I can only see 24-26 psi, and it comes on slower. Fuel pressure is a steady 68 under WOT, ICP is great with the adrenaline (been doing alot of datalogging) There is no real shaft play in the turbo, it sounds good and spools like normal. I am thinking injectors, On initial morning startup I get a white puff of smoke instead of the typical black puff I am accustom to. Inj's are stock woth 196k on em...

Thanks

It could be the stock injectors just wearing out, especially at that mileage. Though as for the boost, you might be moving more air with the EBPV delete so that pressure is traded for air flow.

Yep, I'm thinking injectors. But the boost was 27-28 before with the ebpv gone, it has just decreased as of late. Ebpv has been gone over a year

You also loose some boost with the WW. The stocker makes a little more boost... but its common to get turbo surge.

Right, I had 30-32 before WW, 27-29 after WW install, now over a year later, it has backed off to 24-25 at WOT
