Some turbo tuning questions:

[OrangeMustangGt]

Ok, since a turbo is not a linear boost level like a supercharger, and is load dependet, how does the computer handle this?

Can you just throw in some 42's and a MAF and have a SCT Chip burnt?

Or do you need something that is boost relative like say some 30's and a FMU?

Thanks, just exploring my power adder options.

It would be better to go 42s with a blow thru maf and get a good chip and tune. And fmu will work but its not the better way to go with a turbo. I've seen you over on TM.com so I'd ask there if you haven't already. See what those guys are running. I'll be running 42's, dual walbro pumps, and running megasquirt to tune it and I could get rid of the maf if I wanted and go map.

I'm running 42's, 75mm draw thru MAF, and dual 255's (1 in tank and inline) no FMU. Tuned SCT but going back to the O4 PMS or FAST. I really don't like being married to a tune at all.

JR, what brand maf are you using?

Since im gonna get another maf, what should i shoot for, a draw through or a Blow through? i was thinking that i should stay with pro-m(mass air systems)

I have a Pro-M and a 75mm will be plenty for you , IMO.

You'll get 50/50 answers on style maf to use B/T or D/T. IMO, you should shoot for a draw through style. You can go over to TM.com and read lots about the differences and advantages in using which ever one. I think lots of guys run the B/T just to run a BOV.
Lots claim that the D/T is easier to tune.
