I know that link is a blast from the past but they are wrong! Yes you can run a 2 bar with a maf, and no you will not max out the PE tables nor have huge numbers as said. I tuned my 95 supercharged LT1, Stock PCM, 2 bar back in around 97, absolutely no tip in issues, great drivability, no lag, no surge, Perfect street manners, idle to wot and my A/F was always spot on. I also have 85 lb injectors with a driver. I posted some of this back then and recently and people came in and said BS, cant be done and so on. Some took my advice and replies how easy it was and their car ran way better, The reason you go 2 bar is because 1 bar reads 0 to 14 inches of vacum and 2 bar reads 0 to 14lbs of boost (pressure), perfect for straight out tuning, No having to cut values in half as said, with a 1 bar yes, 2 bar no. Like I said in other post, I even tried 2 mafs, didnt work, also back in the day the kits would instruct you to put the maf on the intake side, I found it better on the pressure side,Now all say to install it on the pressure side (Not cause of me) but thru trial and error. Can you run SD? Of course, do you have to? no. It is all preference..Age ole maxing out the maf, Hmmm, Mine 648 RWHP on pump, 722 RWHP on the fast gas all with in the range of 14lbs..
