so finally figured it out im getting to much fuel when secondaries come on so no boost for me. have a new streetported t2 engine rtek 1.7 and running 550/850cc inj..question is can i tune down the secondaries to be more equivilent to 720cc with a safc? im planning on bigger and better mods in the future and just got new 850cc so im not trying to keep swapping injecters.
sorry for being vague any more info needed to tell me if possible just request and ill provide..
thanks

 

A super AFC can control the injectors I've been running 720/1000 cc injectors on my t2 with a SAFC for the past 3 years @16lbs. boost. Do you already have the SAFC? If you are buying a new one consider upgrading your Rtek to 2.1 instead it has way more features for about the same cost. Before leaning the car out a wideband O2 is a must it's very hard to tune without it. It takes a lot of testing to get all the settings just right for driveability and full power afr's.
