injector sizing and tuning
injector sizing and tuning ordered vengeance racing 226/228 x3 with 918s, a ported ls2 oil pump and am probably about to order a ls6 intake and possibly a stall, llong tube offroad ypipes. my question is what size injectors to i need to run this engine? also, what tuning method do you guys reccomend? weighing a few options wanted to get some opinions on both
either 30 lb svo injectors if you don't plan on really going crazy with mods in the future or 42 lb delphis if big mods/dry shot later on. as for tuning i would probably suggest having it dynotuned unless you are really smart.i tried tuning myself and quickly realized i was way over my head. maybe a simple bolton car wouldn't be to bad but needing a full-out tune was to much to handle 
SVO 30lb injectors will be fine, I wouldn't go much bigger, it'll be overkill unless your wanting to do FI later on. I would defenitly get a good tune, hp tuners or efi live. If your going to try to do it youself I would say go with the efi live, they have online help and will help you evey step of the way.
I had read about a company who, using the handheld predator, allows you to data log the car driving with the predator and then send in the results and they will work with you to get the fuel and spark curves where they need to be. They said it can also adjust for larger injectors. It has real time data logging. IT can do the EGR delete and Post Cat 02 delete as well as AIR delete. Is this a worthwhile option? Not alot of dyno tuner saround town that have good reputations, and this is not a incredibly highly modified car. Just wanted some feedback on something like that vs a proffessional dyno tune. Ive also heard that dyno tuning is not the 1 stop solutions and that driving tuning with data logging is the key to an all around good tune. What do you guys think>?
