I bought hp tuners recently. I have stock ls1 maf had granatelli but sold it buddy mabye should have kept it. I have the twins on order but doubt will be much over 600 engine hp for awhile as think throwing them on stock bottom engine with 5 to 7ps limit.
I assume maf is no problem at this low level of hp.About where does the maf stop working and what speed density do I buy they have all these 1bar,2 bar ,3 bar..I am not planning to every go past 20psi,in fact dont think the fast intakes can go past 20psi anyway. Besides its just a street car.Or should I throw a pace 85 on their to better match the flow of my 90tb and intake?Whats max power anyone has made on the maf? and what speed density do I need to get say 15 to 18 max psi .2 bar is 30psi but heard it gives like half or the rating? So should get 3 bar which could do like 27psi.

MAF has a practical limit of about 430g/sec, which is trivial to hit with the smallest of FI setups. one very lightly modded STS A4 car i tuned pegged MAF at 4800rpm, so if you plan to go beyond that, just do 2bar SD and dont worry.

I'd focus on power level and not a boost level. FWIW - I've run 700 plus on a MAF and I know others have run much more than that. I also wouldn't bother with an aftermarket intake. Plenty have gone 9's or better with an LS6 intake manifold.

Im running 14 psi on a big turbo with a maf.Its been doing fine but Im about to make the swap to speed density

I sold my ls6 and then bought the fast 90 nw 90 and not taking it off just because I am getting turbos. It might have advantage on 408 or 427 not the current 346.And they have taken up to 20psi so not too worried. I think will run mostly around 5 to 7 this coming year on near stock ls1. Then up it to 10 maybe or so daily driving with the 408 or 427 and keep the 15 to 18 stuff for very occasional fun. So still 2 bar sd is what i want or do I need 2.5 or 3 bar. ? Say I never ever want to go past 20psi.but likely 18 is enough.
