OEM Evo BCS w/ #65 pill works great

[scheides]

So my buddy rosey with an IX wants to keep his car stockish under the hood for multiple reasons. Been there, done that, cool. I've been playing with the GM BCS for a while now, and brought up the idea of using a #65 pill with the stock BCS to see how it worked. His car is on a stock tune, and he has a full TBE, no cat. No intake, MBC, nothing else.

So we swapped in the pill tonight, I don't recall where he got it but it was about $20. Kinda spendy, but cheaper than a MBC and GM BCS. This is entirely an experiment, I don't know anyone else around here doing this. So kracka loaded tephra v5 on his car and got him all familiar with NLTS and KnockCEL, etc, and he drove it for a few days.

Tonight we swapped in the pill, the stock airbox sucks of course but we got it in there without too much hassle.

I found some basic settings on evolutionm for this #65 pill that were said to be run at 22psi peak, and upped them a tad, shooting for 23-24psi peak, try to hold that, then taper off as little as possible up top.

Within about 5 iterations or so we got the WGDC table dialed in, and were tailoring the target load table (tephra v5 only has one of each, remember!). We did a few more tuning iterations to get rid of some knock he was getting up top, and leaned the car out a tad as it was running pig rich after 5000rpms. I did not want to go too crazy, as we did not have a wideband, just shooting for about .89 on the narrowband, but we were able to do this with relative ease.

As a result, the car pulls nice and strong, boost is quite steady, and seems to hold at least 20psi by redline. NOT BAD for a car with stock air box and stock paper filter!!!
