DeathByBoost

My setup is a built d16z6, 440cc injectors, walbro fuel pump and a phearable.net chipped P28 basemapped to 11psi. My problem is that i had a T3 that never bogged on me with a tial external wastegate. My new setup is a T25 from a S13 that is used. I wanted to use something smaller and spooled faster. Well, i was running it and off the line with the internal wastegate connected it only goes to 6 psi and won't go past. When i take off the vac. line to the internal wastegate to try up the boost, the car totally bogs down and don't go any where. I don't have my wide band hooked up yet, so i don't know my ratio. Please give me an idea here. Maybe a busted turbo?

There's your problem --> BASEMAP.

It doesn't matter who made, it's still a basemap. You have a wideband, throw it on there.

I don't know why people insist on even starting the engine with a basemap. When I put on injetors, wideband goes on, laptop and all.

If you need to absolutely drive your car, keep the stock injectos and just don't boost.

Agreed, get a wideband in the car before possible damage occurs, the bogging is more than likely due to improper fueling.

That something call boost cut from the basemap my friend, you should be thankful that it even have one.

ok that makes sense, but when i had my t3 on there with an external wastegate it never did any of this and i was running the same fuel management. I was thinkning it was a t25 turbo issue with the internal wastegate. Cause why would this turbo act funny. Maybe boost faster and the basemap doesn't like it.

So does this have anything to do with a messed up turbo?
