red lighted for my 14.01, i'm still counting it! I think the other lane was a light blue NBS single cab turbo truck also
Dyno'd in 4th, it wanted to downshift if he got into it before about 3400rpm (note AFR, fell out the other run)
no tuning today, only had time to get a couple base runs in. they're going to take a look at the tune now and see if they think they can get anything more out of it before I pay for not a whole lot.

Thats where i'm at with it. going to start looking for different wheel/tire, may put a little drop on it, and try hole in stock airbox mod to get that 13 second slip but thats it for NA i think..... next is going to be some FI

Andddd about 5 min from house started running really rough, limped home, popped hood, no codes. Grabbed temp gun...cyl 3 about 100* colder than the rest, plug wire blew out, with insulator still laying on the header.




Grabbed msd set that the end can be bent on, ill throw them on in the morning hopefully that's what the prob was

shop that dyno'd the above never got back to me, ended up taking it to Kraftworks/Excell SPS for dyno tune. I'm pretty easy goin so i just left it up to them to get it tuned at first. got it back, dyno showed over 400hp/400tq but they set up shift points at 6k, didn't do much to the VVT tables, and had it idling low so the cam was choppy. I took it and drove it around for a day it pulled good to the new shift point but i still wasnt very happy with it, brought it back down sat with their tuner for little bit and went over expectations, brought the idle back up and smoothed it out, retarded the cam, brought the shift points up to 6500. Didnt put back on dyno after making those changes so not to sure of numbers... planned to go back to finish up flex fuel tune after i grab/install sensor and will put back on rollers then.

so far its at 13.8@100, 2.0-60' on 93oct, 5900lbs, stock autoride suspension, stock 20s 275/55 nitto crosstrek tires. going to do a little suspension work to see if 60' can get better and i've also never tried launching it with abs fused pulled - using dash button to turn off still left some traction control that would kick in.

before i go back to finish tune I was wondering if there was any other small changes i can make :
intake - currently just have the airraid tube and high flow panel filter in stock box with hole cut in bottom, .I can get the rest of the airraid kit (box cone) or go 4" tube all the way to the TB?
throttle body - port stock size , swap to ported ls3?
exhaust - 1-7/8 longs tubes and ypipe is connected to the stock denali 3.5 exhaust (muffler and resonator). would a cut out help?

had a friend of mine throw some vbands on the SE headers and weld up all the slip joints on the ypipe - with the vbands i can pull the whole ypipe without having to drop the transmission crossmember.

Put on belltech 2/4 lowering kit, replaced the autoride shocks with QA-1s, djm offset sway bar links. front just has a spindle. ran the last few trips to the track with E85, havent done any tuning for it though. More i stiffen up rear shocks the better it keeps going, still wants to hop up though, front will need to be done eventually. i think it's all out of mph too, car 6674.
ordered some new wheels to roll around on most of the time, i'll probably mount a set of 555Rs on the stock wheels

Horsepower is up 26, to 481. Do you attribute that to E85 and the latest tuner?
