Haltech Elite 750 and Adapter Kit

(SNP Speed Innovations)

So let’s say your 4 cylinder Tacoma just isn’t as fun as it was and it’s time to have some fun, so you decide to throw a power adder on it like a turbo, supercharger, nitrous kit, or just maybe a larger set of cams but then the thought comes in “what about managing the engine?”

The next question is what Programmable Engine Management System would be worthy of such a task? What system would be robust enough for the amount of punishment the 2RZ/3RZ lovers can give? What would be reliable, dependable, and sophisticated enough to make sure you make it through your trail, course, or race and not only do so but operate at peak efficiency every time?

5 of 5 Supercharged high boost 2rz December 30, 2020
Reviewer: John Roesch from Gilbert, AZ. United States  
I have an 84 Toyota X-cab 4x4 truck that I swapped a supercharged 2rz in to last year. I used the split second buggy back ECU with the 5th injector and I just wasn’t satisfied with its performance.  It bogged and flat spots, other times it would run great.  I got tired of the inconsistency, so I decided to bite the bullet.   I went with the Haltech 750 and it was a plug-n-play unit with a pig tail. I removed my split second unit and plugged in the Haltech 750.  Wow a huge difference!  Power was right where it should be, no flat spots or sputtering, and very user friendly.  I did call tech support for a “tune check” to make sure fuel trims where safe and where they needed to be.  Gabe was an amazing support and knows his stuff, and willingly offered his expertise.  You definitely get what you pay for and this was the missing piece to my opus.  Thank you LCE and SNP, you guys ROCK!
