Is it just me or is the Big Stuff 3 an out dated useless system? I have one and I have never liked it. I am use to tuning stock PCM with HP Tuners, and I have a lot of time with different Mega Squirt systems and I find the Big Stuff is old and outdated. Loging is a joke. No auto tuning. Very difficult to find whats going on.


What is everyones thoughts on the Holley EFI Dominator system? is it any better? I have a Mega Squirt 3 EXP sitting in a box and I am tempted to cut the Big Stuff out and toss it. My only issue with the Mega Squirt is it will not control the 4L80E trans. If I have to spend money for a separate trans controller I might as well buy a complete modern system.

I don't have it yet but I will be going with the Holley system, Most likely the Dominator.
The Holley system just seems to be more complete and adaptable plus easier to use than any others available. The only major complaint I found was that it didn't work with stock LS coils but that has been fixed for awhile now. My only complaint is the price lol

What's your issue with the stock computer and HP Tuners?

I'm pretty sure you can control the 4l80e with Megashift and connect them together via can bus. http://www.msgpio.com/manuals/mshift/4L80E/4L80.html

Stock computers are limited. Aftermarket controllers (Holley Dominator)offer many advantages not limited to Logging,Two step/Nitrous control/Boost control/Multiple switchable tunes/16 injectors/ Low or High impedance injectors/Timing control/Traction control/ Multiple fuel pump control/Dual wide band... Basically it can control just about anything you need it to.

I'm going with Holley to control a "8+8" 16 injector setup on a LS408 with a 6-71 roots blower with N20... Stock would never work in my case.
