[2.240s]

I have a 89 hb w/,redtop-fmic,boostcontroller,3in exhaust,koyo rad dualfans.If i bolt on a t28 with out upgraded injectors and MAF will i see decent gains??

not realy, your injectors and MAFS are already maxed out using a t-25 so with a bigger turbo you would have to lower the boost to keep it safe. If you upgrade you injectors and MAFS its worth it becuase you can take the t28 to around 18psi and it holds it to redline.

Negatory.

MAFs has repeatedly seen 270whp before it hits 100% voltage.

You will make about 10 - 13% more power with the T28, but don't expect massive gains due to the injectors and MAF running out of capacity.

I have the same set up but I am getting a Afc will that get good gains?

You might gain a little bit with AFC on stock injectors via fine tuning but if you are getting a AFC why not get bigger injectors as well?

I'll have bigger injectors im putting the gti-r motor intake manifold and injectors.
