Ok thanks for any info.

I have a ls1 for a buggy build and want to run low boost like 6 lbs. Does the ls1 have a 2 bar map sensor to read boost? Of I do i need a FMU?

What ratio fmu if i need one?

Thanks guys.

 

Actually you can run 6 lbs with a MAF but if you want to do Speed Density all that you need is a 2 bar... You so don't need a 3 bar tune though because it's going to be used for anything over 14.7psi and up to 29psi... Plus if you're not going to be using it there's no need to go to a 3 bar because your resolution will not be as good as a with a 2 bar map... As far as the injectors, if you're only going with 6lbs then 42lb injectors should be fine but you can find some 60lbers for a little more...

and as far as the fmu....Just get it tuned...
