I've recently installed the RRM piggy back and am looking to increase the fuel delivered to the engine to see if it'll help the "starving" I seem to be noticing in lower RPMs. It seems to really kick after 3500 rpm in each gear. Prior to that, the engine is seeming to want more, but is not getting enough fuel (guess) to put out that power when I floor it. I'm still within that "learning period" with the piggy back ECU stuff (>50 miles). Just curious how large of a fuel injector I should consider purchasing. Seems like most people without a turbo setup dont exceed 400cc. Also plan to purchase/change out spark plugs in conjunction since it's been awhile. I have a 03 OZ Rally with NA setup. Should be putting on a RRM Street front brake kit within the next week as well. Great products.

Current mods as follows:
- Kamikaze Headers
- RRM Front Sway Bar
- DC Sports CAI
- Magnaflow Catback Exhaust
- RRM Piggy Back

Again, looking at increasing from stock fuel injectors (240cc I believe) to something a bit larger to supply more fuel to my current set up. Any spark plug recommendations are appreciated as well (even though I've already done my research). Looking forward to any input as I continue to research the possibilities.

 

Lower RPMs still feel a little "lumpy" at 60miles in.
