do you plan to run a 2 step? the plan for my s10 was going to be to set the 2 step to whetever RPM it launches best and arm the nitrous window to activate 6-800 rpm above the 2step. with a converter my size it will basically be launching off the trans brake on the nitrous.

This is what I would do if you have the fuel system to handle it.

Don't think I haven't thought about it lol.. Cheaper on fuel for me to just run c16 in a stand alone and 91/110 in the fuel cell

Im a little late to this thread but when I priced it, it was even higher then that. That was figuring drive by wire, 4l80 control, low impedance injectors ect. I wanna say around 4500

just adding some more info for those who want it.

It's well worth it!

Doing a TT LSx, 80e, dbw, using the boost controller, meth icg. 5bar

I think the customer is a little over 3K, with all the harnesses, a few options and the wideband sensor.

Some of the trans controller options just make sense; you can tell it's more race inspired.

- note, 411 pcm in the 8's with no tuning issues; fyi

Thanks for the info. Seems like it would be worth it with all the features. But it seems like the dominator is the only way to go with all the I/Os

Lol 4yrs later and i still dont have mine running, but im close i just started thumbing thru new startup tune file yesterday actually. Holley forums and all the previous questions has been where ive found most of my questions answered. And make sure you run the power&ground harness directly to the battery its important. Thats all the help im good for as of now..
also holley has some good videos on there youtube page about various stuff and how to’s
