how much boost will a set of 275 injectors add to my truck, will it be enough that it trips codes?

Bob Wagner

no, you will be fine without a boost fooler unless you toss on a turnbuckle. then you might

A set of RV275s will not add boost unless you do something to override the boost control (turbomaster, boost elbow or turnbuckle). If you do this you will need a boost fooler to keep the ECM from defueling and setting codes. Here is where an Edge EZ or other box, that has a boost fooler will help plus you get the added kick of the box.

my truck did set overboost codes with just the 275`s in it.it didnt throw the check engine light,but it did put the overboost codes in the computer.i just drove it by the guage until i put a fooler back on it.mine would go 26lbs. before the wastegate opened.
