Hey all! Welcome back to my channel. Today I'm unboxing my new Ace's EFI Killshot TBI. I decided to return my Holley Sniper 2 EFI in exchange for this. I gotta say, I'm very impressed so far. Once the RX-7 is put back together I'll be doing videos on the install, first start up and tuning process. Any comments, advice or words of caution would be greatly appreciated. I've never tuned a car before, but I guess the only way to learn it to do it and break stuff. Subscribe and like and stuff and follow along! Thanks for watching! #holleyefi #acesefi #rotaryengine #mazda #rx7 #car #80s
