Questions & Answers Ask a Product Question

Hi, I have a 1967 Buick Skylark with a 300ci 2bbl carb. Will this system mount on my current manifold? I read somewhere I may need an adapter to fit a R2G manifold. Is this available what I need and is it available from Fitech? Thanks in advance.

Asked by PAUL on December 15, 2018


The throttle body is Holley 2bbl. So yes a adapter is needed,mr gasket #/1937.

will this unit work ok on a 1800 cc subaru boxer engine as i am thinking of super charging one.

Asked by WARWICK on May 04, 2019


This system will run on any engine as long as you can provide a digital tach signal to it. This kit will not support boost however.

Posting this review after 3 1/2 months of frustration and complete useless behaviour of this "self learning" EFI. I Bought this in September after drinking their coolaid. It has to be the most frustrating, finicky, unreliable and completely unsupported aftermarket equipment ever sold. I had issues with the engine not running correctly after installing and contacted the manufacturers support - that was the beginning of October; still no response. Have tried numerous forums - no satisfactory answers. The unit will work briefly then go to complete **** after a short drive. It has never worked long enough to complete even the minimum driving for a basic learn. I will remove this equipment and go back to carburetor- the vehicle drove beautifully on carb and never gave any issues. I may buy the competitors unit and see how that goes. I do like the idea of EFI on my old classic, but not this one; it has been pure frustration from the first turn of the key after installing. more
