The key word you said is Yet. Others have gone well into the 9's with a maxeffort system, others get several chips burned and are content with that. If you want programmable ECU you can do yourself as your combo changes this will work well. It has other features for a street car the old FAST didn't have. I honestly do not think you will be upset you made the purchase of a programmable ECU. I think you can hold off with your current setup, but if you plan on stepping things up at some other point you will be looking again. It is 100% up to you I don't want to push you into something if you are not ready.
