I don't know about their tuning, but I assume he's supplying you an ECU for the price? When you break it down,

860
-125(cost of buying an ecm)
=735
-125 (tune)
=610
-550(harness)
= ~60 shipping/tax/misc

If you figure thats all estimates, but if it works out.


If any of yall are in the upper midwest, I can get ur stuff tuned locally for cheaper (but then I own your soul, so its a give/take)

Yes that was for everything including the ecm....reading his website, guy seems passionate about his work and harnesses look pretty good...not sure what route im going to take yet

thats a lot of cash!!! id get a blazer tank, then you can use a sending unit from it and run a walbro pump, and it would be a lot easier I'm sure....plus cheaper... i think your running a return less system...so that would be easiest i think...and cheaper!!!

We used a 91 Jeep Wrangler tank in ours. Fits like it grew there. Also can be ordered EFI with baffles and with an EFI ready sender setup for the 381 pump. Look up the "Silver Dollar" thread with the search function. Worked good. Tank was $90ish from Summit. Good luck!

I think I've seen places that sell the head and tailght harnesses, but it's been awhile, I thought about doing the same thing, since I was in there, but once I got behind the loom and the wires are great so wasn't worried about it
