LSX/TPIS 90mm TB - worth it behind stock MAF ?
Did search, didn't find good answer.
Obviously the MAF is a restriction, but what do you guys think about the LSX/TPIS 90mm TB replacing my Holley intake and Jantzer TB ?
222/224 .571"/.571" 114 LSA Cam Motion cam, Stage 2 5.3L heads milled .030. Makes 410rwhp/415rwtq N/A on a DynoJet. (No dyno #'s on the hose yet).
Guesses at gains and will it be worth it to spend the $$ ?
I'm leery of changing MAFs - anyone have good things to say about the 85mm GMAF or SLP MAF ?
I know bigger N2O and fuel pills are much cheaper.
(Seriously, need opinions/info on the intake/tb).
Thanks !

I know some people running the SLP 85mm maf with the 90/90 combo and say it works great (tunable). However, if you pull the screen out of your stock maf, there wont be THAT much of a difference. I believe Jason told me it was worth 2 rwhp on his car.

I have the slp 85mm MAF and am very happy with it. I am going to be changing my set up this spring. Putting TEA heads and Futral 114 with LSX 90mm Intake and T.B. so we'll see how everything works together. But you can see my current mods and the slp 85mm MAF is good imo.

I use the slp 85 MM maf and it is working out pretty good, I actually took it off one day and swapped it out with my stock descreened MAF just to see if I saw a difference in a/f and I did not. Even with this said I would still re dyno tune it with the 85 MM maf and 90 MM TB just to be safe.
