Turbo BS Thread

Looks like you got it running right for not tuned on large injectors

 

Yum! Now that's what I call wastegate priority lol

Run them blankets!!

What do you think the effect would be in hot areas like here in AZ?

 

All mocked up.

 

Time to back-purge and weld up.

 

Shiiiiiiiiiiiiet...

 

Looking good. What are those blue hoses? Oil?

 

Coolant

 

That was my other guess. Had to be one of the two.

 

Blue, cause they're

 

I did another vac/ boost leak check today after work and sure enough there’s a leak in the same area (IAC valve). It looks like it’s coming form the electrical connector and housing. From 10psi to 5psi the needle on the gauge moves fairly quickly then after 5psi it’s a lot slower. I’m thinking new IAC valve Instead of more fipg. Either way a leak is a leak besides I think it’s causing the stumble and backfire I get when I let off the throttle and then go back in it.https://youtu.be/OkQ7xCTcKbg

 

Mine will shoot out a fireball between gears if I'm going balls out. Just the lag of the system I think.

 

On the street it does pretty good after it’s really warmed up. It’s on the freeway where a lot of times if I’m easing into the throttle like to pass the afr’s suddenly go to 8.8-9.5 and it surges slightly keep in mind that’s 1/4-1/2 throttle on the freeway in overdrive. When I go WOT it goes fine but not good. This has been intermittent but most of the time now. I’m assuming I could reset the ECU maybe it needs to relearn everything but is it just a matter of disconnecting the battery for a curtain time. Of course I’ve done that but maybe not long enough.

 

That's probably when your ecu switches to open loop. Mine pops into OL cruising up a mellow hill 2300rpms. It's good that they go into OL easy.

 

That must be where the tuning would come in handy

 

I still got that AEM FIC

 

If you are on the fwy in overdrive, give it just enough gas to make you accelerate. You can feel the truck switch to open loop and your afr just drop.

Ease off the gas and can feel it go to closed.

Once this started bugging me that when I did the piggyback.

 

Thx I feel better now knowing exactly what it is and it's true if I let off the gas steady it goes back.
