Yea definitely not a good idea. Maybe if you have a variable meth controller w/100% and 2 large nozzles and really watch the afr gauge.

dang is it really that sensitive to the boost ?

if you put 6-8 #'s on any NA vehicle with factory tuning its not gonna end well

devic

can u get tune's so that u dont have to run the boost and it with still operate normally
?

I'd just advise you don't try to do boost at all.

devic

i just need to know if u can tune the pcm, so that it will operate under boost , and no boost

Stick with the mods on your Sig.

Your nowhere near ready for a boosted motor.

Keep reading, we are not trying to be ******** here but you got a long ways to go before you consider boost.

to answer this question, a pcm tuned for a boosted motor will run off boost and boost (over 100kpa at sea level). But you can't run a pcm tuned for just n/a and boost it because it will :bomb

Actually,
You can run on the stock tune, with low boost, 5,6 o.r less psi.
But u will need an fmu, return fuel fpr at the rail,larger injectors and fuel pump upgrade at a minimum. Many sc/tc kits were sold with a fmu for fuel enrichment under boost. so is it possible, to run on the stock tune. With or without boost, since the fmu provides a huge amount of fuel pressure/volume at the injectors. But is not optimal for a real high hp motor.
There is no real substitute for a proper tune, and a return fuel system with a rrfpr for a serious forced induction build and a complete recalibration of the tune. No way around it.

im just asking to kinda find out where i want to go with my car, i plan on getting a cam, and i can fab up my own system just not sure as far as the tuning aspect of it goes

and im kinda wanting the turbo to just be on demand kinda not in use all the time

devic

if i switch over to speed density will it make this easier, than running off the maf and the map sensor ?

devic

and doesn't some 1 make a fuel regulator the ups the ratio of fuel vs boost, there for no longer needing a tune at low levels ?
