Depends which Megasquirt system are you looking at. You can buy a $300 Microsquirt and have full spark/fuel tuning capability (and some other features, but its limited) or you can get a $1200 MS3Pro have get more features than Holley can offer. Mainly depends on how much you want to spend and how much work you are willing to do. Most MS systems will require you to build your own harness, unless you go with a unit from EFI Source.

so if I'm going for easy instillation go holly if I'm going for performance and tunability I should go MS. Also gotta take in mind that it's for a turbo build just wanna get the best for the money really willing to spend more on the harness than anything.
I bought the Holley system. One of my deciding factors is that I'm not familiar with tuning and the tuner that has been doing the programming on my car really likes Holley. So if you do your own tuning then I would look at the instruction manuals for both units and see which one you feel comfortable with. If you have somebody else do the tuning, maybe ask them which one they would recommend. Either system looks awesome though so you're not going to be unhappy either way I'm sure.

Not how it is at all, MS is cheaper but not as user friendly. They will both do most anything a hardcore setup would ever need. Neither is lacking in the performance dept. I went with Holley for ease of use and it's more refined than MS.
I don't know much about Mega Squirt, please tell me how and why its better than the likes of FAST XFi or Holley Dominator EFi systems? I feel the Dominator system specifically offers an all in one Control System capable of tuning the most advanced machines you could dream of building and offering Data Logging built in to boot.... Harnesses, Sensors, and Data Inputs to cover the needs of the most demanding Competitor... Please let me know cause FAST & Dominator EFi systems with Dual Wide Band O2 NTK sensors for added heat and all required harnesess are not cheap... yet I know what I will have with them....
Does the MS Gold box have the option of DBW (1 or 2), dual WB O2s, flex fuel, injector end angle tunability based on RPM and load, auto trans control, PWM cooling fan control, boost control, nitrous control, and dozens of user definable inputs and outputs?

I recently toyed with the same issue for my turbo setup and went with the MS Gold and it does a ton. I'm not sure about the DBW and injector angle, but yes it will do two WBO2S and everything else including, 2 step, bump box, fan control, fuel pump, alt, control trans brake (microsquirt trans controller is seperate), traction control, etc, etc, the list goes on. Google some videos of Denmah using most of the features on his builds. I debated the Dominator system but upon calling them and getting a page long list of parts that added up to just under $4000, I opted for the Gold LSX plug n Play for $1250. Both systems are pretty user friendly, preference between one or the other usually is familiarity IMO.

I have only used Big Stuff 3 systems up till now. I built a S10 street car and was doing so on a budget. I went with the Ms3 gold box and Microsqurit Trans controller from Efi Source. At a cost of 1500.00 for everything. The plug and play harness was good quality and i had the whole thing installed and running a day. I would say its every bit as good as a BS3 for 1/3 the cost. Very simple to use the Tunerstudio software is very user friendly and layed out nice. They supplied me with a few base tunes that got me up and going for a Ls turbo. Tech support was also very good.
Flawed thinking.. As mentioned, do a compare.
