New 355 LT1 MAF top end problems I just got done putting together a 355 LT1. It is all forged I stepped up from a. 225/233 cam to a 23*/23* type grind along with 200cc LT1 heads. I also run 200+HP of NOS. With the previous 350 and the same setup the car sucked in almost 1000 CFM via a GM tec 2 scanner pulling through 4th to traps on NOS. New setup runs fine until top of 4th on NOS when it posts an ses light with a P100. We clear it and car runs fine. Question is do I get a new SLP maf w/ 100 more of CFM. Disable the MAF in tunercats? What do I do please help, kind of perplexed..

So what your saying is to run the car in open loop all the time, or just disable it at the track for nos. I would still like to use the maf as the car does see some street time. Big HP LTs let me know what u guys do, looking at several possible solutions but all involve keeping the factory computer and tunercats.
