Time to upgrade injectors??
 

Doing a dod delete with a new cam. Wanting to know if I will have to get the 8.1L injectors. Would like to know before I get it tuned.
comp cam 54-450-11
lobe separation 115
intake center line 111
duration. Intake 260
Exhaust 266
Lift. Valve intake .513
Valve exhaust .520
Lift. Lobe intake .302
Lobe exhaust .306
Basically a stock engine now and don't have any plans of making it a race truck.

I would say no.

If your truck is flex fuel, the injectors are good up to about 10psi (if boosted). Since you're NA, don't worry about them.

It is not a flex fuel. So I think that they are a little smaller.

If you're doing a DOD delete, you have a newer truck and I would almost guarantee that you have FF capability.

Either way, you should be fine.

08 not flex
injector size 25

I would install flex fuel injectors or get larger ones just to be safe.

Here's a link for some 30s...

I have 8.1L truck injectors in my LQ4. Last dyno, still had plenty of injector left.
