Default LSX parts on my 5.3L

Here is the list of mods being done over the weekend...

1. Ported LS2 Inake Manifold
2. Ported LS2 Throttle Body
3. LS2 Fuel Rail with 42lb. Injectors
4. tr220 Cam
5. Diablo Tuner
6. Corvette Servo

What else will i need to do this swap? Will the injectors need a spliced harness? Will i need the LS2 MAF? TPS?

you will need more than a diablo tuner to make this work. TRUST me.

Unless you are making 500 rwhp there is no need for 42lb injectors. don't waste you time with the diablo tuner. Same goes for the corvette servo. Get a proper build for your transmission. If you do decide to put the injectors in, what brand are they?
I may be wrong, but I don't believe the diablo tuner can compensate for the larger injectors. You will need Hp tuners or ls1 edit, ect.

ls1 edit was an example. I was only telling him the he will need more than the diablo. if you think the vette servo is the way to go, have at it.

Never heard of anybody installing a Vette servo and saying it was a bad mod (unless of course the tranny case broke or something lol)

well the injetors are oem along with rail from GM.. from an LS2. Also I have a diablo for the time being and it does have settings for injector size (% Larger, or % Smaller). This affects LTFT and Injector size.
