5psi on stock ls1
Like the thread says, i plan on putting 5psi from a STS remote system with a FMIC. Im getting 42lbs injectors and a new PCM so i dont have to self tune. With a new PCM tune will an LS1 in a 02 t/a be able to handle it? i dotn wanna blow a motor.

There are tons of threads but I think the consensus you will get here is "yeah, no problem. go for it". Some members in recent threads have said they are running 10-12 psi and have been for a couple years with no problems. As always, be conscientious of what you have and you will be fine.

I have had the STS kit on my stock motor 02 Z28 for about a year and a half at 5 psi- 10 psi with no problems. I have a dual stage boost controller so I switch between levels. I would say it's not a problem as long as it's tuned properly and you take care of it.

5psi is incredibly easy to do, just make sure the tune is good...18-20 degrees of timing and 11.5-11.8 AFR is safe within boost.
Fuel pump is suggested though and I would go with the TRT FMIC for some more power. At 5psi, you'll only be putting down maybe 410/415 at the wheels. Trust me, you'll want more

Don't go to Nelson Perf. When i got my car Dyno tuned at Vengence Racing , they asked me if I ever had a tune I said yeah. They looked at me and smiled and told me nothing had been changed. If you live in the Atlanta area thats the place to go.

no, dont drive you car without a tune at all. Thats a quick way to pop your motor. If you have to limp it to a shop for a tune send it in for a mail in first so they can set you up with a close tune and have them fine tune it once you get there.

Not saying this is what you should do but I have been running my oem f/p from the get go and never had any issues with lean conditions, but I carefully watch a/f and fuel pressure. When installing I tested and made sure that I had enough fuel pressure and volume just to avoid trouble but I am installing a larger pump this week.
I also agree on cutting an access hole to the fuel pump as "sevanseriesta" stated I have done pumps in F-body's both ways and the access hole is the way to go!!!

Also you could get a bigger TB if you choose but it won't improve too much unless you have a larger opening to the intake to let that air in thus a larger intake is needed. Just my 0.02
