Procharger MAF Smoother? I am installing a used Procharger kit on my 96 Corvette. These old kits didnt come with a Tune, they just upped the fuel pressure with an external FMU.
However for 96 models they came with a MAF smoother. Anyone know what this thing does and why its only required on the 96 models?
I intend to tune mine via JET DST. Wondering If tuning the maf would negate the need for the MAF smoother?
If all else fails I can go speed density but would prefer to use a MAF.
Thanks
Dave

I never thought you would want to really use a maf sensor for boost. As ive only read forums, others have explained that the maf will only read the flow of the air but not actually notice how dense the air is, hence people choosing to use map for boost.
As Im sure you know, the smoother is to deal with the turbulent air, but I was assume that the turbulent air is not stable air, so even if the maf is tuned for boost, there would be inconsistencies with the air flow against the maf sensor which then would just cause inaccurate readings.

As to the 96 vette question, I assume that is the only year in the vette that had obd2 since 97 brought the ls. (F-body kept the lt for 97)
could be an issue of trying to keep the kit emissions legal.
I would contact Solomon for help and a tune. He has always done me right on my LT. I have DST but to my mind the LT is more of a pain to tune than LS with HPT.

I have never boosted my own lt1 before, nor am I running the lt1 pcm anymore however there are plenty of examples of running a 2 or 3 bar map sensor with the lt1 pcm. Though what also has been stated is that the accuracy of the pcm greatly diminishes with each bar you go up. It’s possible just not the best.
Do you think the the maf will even care about having or not having a maf smoother when tuned ?

My boosted LT1 is converted to a 95 OBD1 PCM, 2 bar map and I have tuner cats on hand to tune it. I have yet to use it yet as the PO did all the previous tuning. Its currently sitting dormant waiting on funds for a clutch referb.
Also, no MAF on mine.

Im asking these questions for two reasons:
1. I dont have the MAF smoother, its $250 from procharger, I dont want to purchase if its not needed once tuned. My fear was that the singnal gets saturated without the smoother regardless of tune.
2. I dont really want to run the supplied intake, I would like to use a new card style MAF and relocate it to the intercooler outlet. This would allow me to ditch the Procharger intake piping (its clumsy), and dump the blow off valve to atmosphere vs back into the intake.
I know, I could just run speed density and save myself allot of trouble, apparently I like trouble.

I contacted Solomon a few months ago, Solomon said he would tune it Speed Density. Im sure he would be willing to also MAF tune if I asked, but I didn't elaborate after our initial communication.

Maybe you have already looked into it, but is there even a program, OS or person that will tune an OBD2 with MAF for the LT1? From what I have read because there are so few of these that there is basically no support for the OBD2 LT1 cars.
