Streetz Dyno (Low boost)
dyno differences and auto vs manual notwithstanding, the numbers seem lower than I'd expect.
I was wondering if you were referencing it off the turbo and perhaps losing a bunch of boost through lots of piping and your intercooler by the time it got to your engine, but i guess not.

Well the wastegate reference is from the compressor housing, but via manual controller I have it at 11-12psi (well 10 on the dyno). At first i was very disappointed with the result, however 8.8:1 compression, auto, missing like no tomorrow and 10psi. 380 is not too bad in my opinion.
i mean it could be a low reading dyno and I don't know what your torque converter setup is, that can rob lots of power on a dyno (and I'm used to looking at manual trans dynos anyways, with their lower % power loss) so that could be a contributing factor to numbers that at first glance seem low to me at first glance.

I second the numbers being low for 10 pounds on an engine running properly but with the compression ratio and missfires, who knows. Auto FTL too
def could put down 450 with an M/T and missfiring issues taken care of.

Well in comparison 95blkmax put out 370something at 9psi with a 5sp. Same turbo setup, 3.5 and stock compression. so just 1psi more, auto, and lower compression, 380 not so bad. Anyway it makes alot more power considering the miss really hurt the final output.
how do you plan to put all that down is what we should really be asking you with those kinda numbers
Streetz., happy you finally dyno....lmao at the comment about making 450 at 10 psi...hmmm yesh still havent seen that dyno graph. 380 for your engine at that compression seem really good to me bro. not tune it and dyno at higher psi and put up those above 500 numbers (: question what gear is that run at???? graph can be confusing,almost looks like a 4th gear pull. oh its ALvaro by the way.. StillenMax forgot to log out lol

maybe I should keep my car and go to the low cr side of the world.
or maybe you should paypal me the $25 you still owe me from over a year ago?
LOL. well misfire aint gone yet, im going to measure voltage at the volt booster thing I got, its not terrible like before, but still there occasionally. Might also be to little timing, with low compression, 93oct + meth, 20deg might be too low for 10-11psi. Today I put up the boost a couple of psi and felt great, didnt feel a miss this time but going to test more.
Did some tuning today. Took off the muffler, adjusted timing a little so it woudlnt retard so much. Went for a drive and man it pulls hard! I feel a misfire or two at around 4,000 rpm, its a little lean there at low 12's, which I now fixed and hopefully its gone. With no muffler boost is now at 13.6psi solid, afr's in the 11s. MAF incoming voltage went from 4.50's to 4.70+, so there a good amount of additional flow (which means turbo still efficient, when voltage drops after increasing boost, then that will tell me the turbo is not flowing enough). The thing pulls HARD! Even tranny noticed more power, temp went up quick.
