To my understanding, 128 BLM is whatever you set "STIOCH" to in scalars...

So if you set it to 15.3:1 in the computer 128 is 15.3:1.. Could be wrong but pretty sure i am right.

I am just saying that a good wideband is the (ONLY WAY) to go.. Sure idle ya want somewhat leaner, especially if you don't have converters.. No reason to own a vehicle that burns ya eyes out idling. That is crazy. But driving around you want those tables close to 128 so the computer isn't struggling to keep it near whatever you set stioch at..... Then for power, you can work the P.E mode to give ya what ya want..

Yeah i get the whole "14:!" may not be great, one guy claims he gets best mileage and power at 13.x:1.. Saw it at thirdgen.org. All i am saying is don't trust just BLM for tuning...

I'm actually thinking of doing a single 4" converter when i upgrade and supercharge everything. I mean yeah i will lose some power, but how much ya need past 530whpo?!? I mean honestly!?!?
