do i need a tune? ok so i picked up a lunati cam Specs. lift .576 in, .598 ex. Duration 221 in, 230 ex. Ratio 1.7. Lobe seperation 114, and i have slp lid, flowmaster and msd wires do i need a tune or can i run it as is and tune it later?
I am sorry, I can not believe the amount of people who ask this question. The PCM will not learn ditly for WOT. The answer to your question is YES! You will see, put it in, it might start up, it might not, it might want to die at the light, it might not, what ever it does, the volumetric efficince of the engine will change and the PCM will need to be tuned to match so it will not die at the light, it will start and run right, and the WOT fueling will be correct.
Even if you went from a stock LS1 cam to a LS6 cam it needs to be tuned to run right.

A top of the line tuning software like HP Tuner or EFI Live will cost about 650ish, then you will need a good Wide Band O2 sensor, they run around 400 or so. So to get set up to tune right you are looking at a little over 1000 bones. Then it might take you a year or two to learn what you need to make your tuning work right. Then there are tuning schools that will cost you a crap pot load, not to mention data files for different things like injector data that will cost you even more. Thn to be realy good who knows how long that will take. I have been tuning for over 5 years. I started with LS1Edit, then switched (thank God) to HP Tuner. I waisted my time and money on LS1Edit.
So long story short, unless you plan on never being finished modifying your car, and you see a need to tune for the long hall, you need to find a profesional that comes with alot of recomendations and have plenty of patience.

thanks so much for the input u r right im not ready to tune my self and dont have the money to buy one for my self (would like to but cant) i have a friend in the springs that has a dyno and i think he has the stuff to tune as well..
Good choice to have it tuned, and getting it retuned for heads will not be expensive nor hard for the tuner to do for you. Just make sure the tuner has a great reputation and you will be very pleased.
I just did 243 heads with a 588 lift 228 duration and the thing barely made it to the shop.
just wait till you can dyno tune it. best way. handhelds and programmers are generally garbage. If you don't know what you are doing completely you can really hurt performance as well as your engine. You don't want to end up advancing that cam too far and really getting up a creek.
Hell no they are not worth it. You are customizing your setup, you have to have a custom tune.
Sorry for the sarcasume, but this question gets asked 200 times a month, and all of them want the cheap way out like you so they do not say "ok great were is my closest tuner?", they always come back and ask more of the same question like you are doing and not wanting to except the answer given.
Yes you need to take your car to a profesional tuner and pay him to take care of your tune.
I was just trying to throw some sarcastic humor in there. Nothing personal to you. You could learn how to tune with HP or EFI, its not hard to do, it just is very confusing at first, then it all of a sudden makes complete sense. I am sure you want to spend good money on other parts right now and need/want to get this thing up and running right fast. So have a pro do it (it does not have to be dyno tuned, some tune them at the track) first. I have found that they can only do so much in the short time they have your car. The will be able to get the WOT perfect, but sometimes you have to spend alot of time driving, scanning, and tuning the car to get it to drive perfectly. If this turns out to be the case for you, then you might have no other choice but to invest in one of the two tuning packeges and start learning to do it. At any rate, let the pro get you up and going with all of your mods, then later if you get some extra money, buy one of the two programs and start fine tuning it. Once you have some time tuning it you will be able to do your own tunes after major mods like you are in the proces of doing now.
The only programs I know of that give you the most tuning power is LS1Edit, HP Tuners, and EFI Live. Stay away from LS1Edit, its a powerfull program but it does not have any scanning software that is worth anything. HP and EFi are pretty much equal and they are the best options.
Oh, and if you want those stickers, I have a sale going on right now, buy 20 of them and you will go back in time you will be so fast!
Good luck and keep us posted on your progress.
