I just started getting into fuel injection a year ago my previous builds were carburetor v8 ' s learned a lot so far but I know there is so much more to learn. But I have had a lot of help from what I would call geniuses like Ash at ash-specs performance and tuning who did my ecu upgrades I recommend him if you need to get some professional tunning. My build I have now is 1994 honda civic dx 1.5L automatic converted to a 1.6 5 speed manual with a great tune 130 mph in 4th no struggle. turbo is in the future any suggestions or advice is greatly appreciated or even maybe I can help you out
