Researched my little brain out. 100 different answers. HELP!! - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Heres the story. My 2010 LS3 has the usual upgrades. Ededlbrock E-force, Vector motorsports 2.5 cam kit, SLP long tubes and cats (kinda), Lingenfelter dual fuel pump, GMPP mufflers. So my question.....dyno made 582 RWHP and 527 RWT. not too bad on pump gas. By the time the dyno runs were done we kinda destroyed the high flow cats, the guts were just rattling around so I cleaned them out. I asked when we got done about boost numbers and A/F ratio. I guess they dont print that out but he said "you have no fuel issues at all" I trust the guys at Vector a ton, so off I went. No problems and the car has ran spot on. I would like to run a smaller pulley but am curious if the 52lb injectors are up to the task. Not looking for all out power but a "safe" richer tune. What is the max (reasnable) horsepower the 52lb injectors will make???

I would think you are about at a %100 duty cycle on 52lb injectors already.

You are at the max I would want to go with those injectors.

Thanks for the info..guess I need more research. According to that site, I need at least 65lb.

Without guessing, let the tuner hook up his tuning software and read the injector duty cycle at high rpm WOT, that way you know for sure.

Are you returnless or return? Wouldnt be a bad idea to install 65lbs but make sure you can get the injector data for whichever injector you choose to go with.

Get some ID850,s. With the setup you have you'll be good to go on fuel for pretty much anything you do in the future.

I would have to agree with the ID850 injectors as well...

coptzr · 01-26-2013, 04:20 PM

I have a returnless system. At what point do I convert?? And I did some research as well on the ID850's...looks like a good choice. Who has the best deals?

coptzr · 01-26-2013, 04:21 PM

Also considering a different tuner...Love the guys at Vector, guess I felt like I didnt get all the data needed. Any suggestions in Michigan?

The Stig · 01-26-2013, 04:31 PM

remote tune from Ted?

ayousef · 01-26-2013, 04:34 PM

ID850s are good, and you get the injector data as well. Im sure alot of shops can sell you those injectors, I get all my stuff from New Era Performance in NY.

Id850s are over priced. Everyone told me I needed those to. Went with the FIC 65lb injectors and used the data he sent and they work great. FIC has bigger injectors to if needed.

Mchlgrrsn · 01-26-2013, 09:39 PM

Bigger injectors will let you raise the rev limiter. I believe the magic number is 600 rwhp where it becomes necessary.
