S475 single spool up

[durawhore]

How big of a difference will I notice between a S475 .90 vs 1.10 ar I'm running a sc 1058 converter. Is it going to be a laggy pig with 1.10ar and my old tunes built for 75 or a stocker reason I ask is my tuner is outta town at the moment and I'm putting my truck back together today

Depends on turbine

Elevation?

 

[hondarider552]

I lost 200 rpm from .90 to 1.10

 

[durawhore]

Its, together and it's a laggy wagon

Mine is not to bad unless I am at low rpms in a higher gear.

 

[hondarider552]

Could be worse, my boost gauge does not move off 0 untill 2500 :roflmao:

 

[paint94979]

what engine do you have

 

[durawhore]

Lly...
Okay laggy isn't the correct word doesn't even pull runs like complete shit

 

[Ne-max]

Just wait for your updated tunes. That will make a huge difference. I am happy with mine with Korys tunes.

 

[durawhore]

Fml.. I sure hope new tunes fixes this issue

 

[Ne-max]

No matter what it is not going to spool as fast as your twins did

 

[durawhore]

Oh I know truck has no top end just a shit ton of smoke

While waiting on tunes, test for boost leaks.

 

[plowboy_lbz]

How fuel are you throwing at this thing? Injectors? Pump/pumps?

If you have a 5" intake now, your MAF isn't scaled for the increase in airflow. It won't run correctly until you get updated tunes.

[durawhore]
