No, I messed up my AFR equation (bringing wideband in through a 5v in PCM), had it reading a full point off, so what I thought was ~11:1 was really 10:1 which is the lowest it'd read (so it was even lower then 10:1 afr when going into boost). Fixed the equation, got the afr in check, and she runs like a top (but I did change to some BR7EF's while I was at it)

I know it's only 2-3psi (per log), but it's 50* outside, I'm on totally cold ET street radials that have 25psi in them, no t-brake, no 2-step, and a big 1.32ar t6 turbo, shocked it built any boost. Gives me hope that when I get a 2-step on her I might have a chance for some decent 60' times without a t-brake. Oh, and don't make fun of my ghetto boost gauge mount (in a/c vent), just waiting for my roll cage mount cup to come in so I can permanently mount it.

i have a 6.0 and s475 as well but 1.10 ar...i could build 2-3 psi as well on footbrake with no 2 step at 2800 (about as high as itll go without pushing) but with the 2step and same rpm it makes 6 psi.....2.1 60 compared to 1.7 60 in my heavy beast

went to kdale tonight, typical sunday night at the dale so the track wasn't great, but did get to got wot for the back half of the track. went 6.50 @ 108mph
here is what the tps looked like, i had to pedal it bad for the front half
green line is tps, you can see me stall it up, then pedal the first half, then wot for the back half.
here is the video

Wow, just went back through my logs from last night, IAT's went from 117* at the start of the run to 153* at the end, total advance for the run was only 5.5* w/all the timing that was pulled out by my advance vs. iat table.
i guess i gotta get the meth hooked up before i really hurt something. feeling better about the 6.5 though, less then half track of wot, 5.5* of advance and a fat 10.7-10.9 afr.

~14psi (was showing right at 200kpa). no meth (but will be hooked up next time out after looking at my iat's). per the log i launced with almost no boost (need that 2 step) @ 28.6 seconds into the log and didn't see full boost until 32.9, so 4.3 seconds into the run before i went WOT.

Keep us posted on the two step. I am considering one for my turbo Chevy II. I can't get it to build boost without pushing the car. Going to install a hydroboost brake booster first though.

took it to our local track last night, we've had a ton of rain this past week and the track just wasn't prepped, everyone seemed to be fighting it all night. i couldn't leave with any boost at all, tried 2 passes on the 2 step and spun hard, then tried off the 2 step (just footbrake) still spun, finally tried a pass with no boost and hooked (although log shows i pedaled once out of the hole).
went 6.3 @ 114mph, mph seems to be coming in, but with no track i couldn't do much tweaking. i haven't turned up the timing at all since i added the meth injection (still only 12* advance). probably going to take it out next weekend and see if the track is better, if not we have an event coming up on march 3rd at another local track that seems to do a better job prepping the track. this was my first outing on the et street radials btw (still have some learning to do there as well).
