Ive been studying these forums to figure out how to tune my Kenne Bell. Im pretty sure my optmizer is shot and as of now the budget is pretty tight due to school. When running boost, my truck runs really lean unless im in high speeds i do not get any boost.

I was thinking about larger injectors and maybe a 2 bar map sensor.

What size injectors should I run?
Will Tom Fox be able to flash me for the new injectors.. I spent a decent amount of cash for this project and would like to see it running right.

I know nothing about ccomputers and tuning so anything will help.
Thanks alot

A set of 42 lb/hr injectors can easily support 440 hp (conservative number) at the stock fuel pressure. And a 2 bar MAP sensor would definitely be a good idea for more precise control on boost. I can't answer about what Tom Fox can program the ECU for, although it shouldn't take a big change there.

sweet thanks as long as Tom can tune this I'll be all set

Do you have a wideband? What gauges do you have? Do you have the ability to datalog?

nope running a narrow right now. I am going to switch over and I am completely clueless when it comes it data logging.

Would these injectors work?

Sorry if I missed it but I don't know much about your setup and I am going to say what you have probably heard before, please get a wideband. Also, there are some decent fuel injector calculators online. Are you running auxilliary injectors? How many pounds of boost? Are you watching fuel pressure? I honestly need more info before I can point you in a direction.

Those would top out at around 320-370 hp on a supercharged motor depending on your particular air/fuel ratio. You'd also need to swap the connectors on your wiring harness as the plugs on them don't match.

Before you get too far, there is no way to tune properly for a 2-bar using the stock ecm. You will need to step-up to an aftermarket computer.

SCT will kinda tune for a 2-bar, and may be ok for you if you aren't a perfectionist.

Ok i have been looking online for widebands and found this

I dont have any experience in data logging but im sure I can figure some of this out.

As far as needing SCT for the 2-bar, forget it SCT is too much money and from what i have heard its too problematic. Not worth it for only 6psi of boost

anyone?

I am running the 42 lb injectors, and using an SCT tune, from hemifeaver, ad its running great
