rb20det power loss

[jesse0357]

Ok so after hours of searching im still somewhat stumped. I have a couple of ideas what may be my problem, anyways as title says I get a power loss right after I hit full boost (13psi) I either think its my maf that cant hadle the amout of air flow or my fuel pump isnt keeping up or starting to fail its a 255lph. What else could it be, any thoughts? Ive done all the normal easier tests TPS, boost leaks, vac leaks, ect. Btw my rb20 has a rebuilt rb25 turbo. Ive pm carl H he tuned my ecu just waiting to hear back from him.

Try turning boost down see if it goes away

boost is turned all the way down ists right about 12psi right now. it was worse running more boost though, thats why i suspected mafs

You could be maxing out the injectors if your running stock RB20 injectors. They are only 270cc and really good for maybe 250whp or 260whp.

That was another possible issue I thought too. Maybe just running out of fuel. Im going to be swapping in 650cc injectors but wanted to wait until I did the turbo too that was I wouldn't have to send my ecu to carl H and waist that extra tune.

put a wideband on it..

I'd definatly figure out the cause asap.. beating on it to get it to happen could be damaging the engine

I know Ive had a brand new aem wideband sitting on a shelf in my garage for like 6 months. I need to have the o2 bung welded on my exhaust for the sensor also put my test pipe back in. Maybe this weekend. I honestly dont know how to read them though :/ probably easy id guess
