Default 07 WRX VF48 1/4 mile results!

Hi guys, so heres the story. Car is a 07 wrx tr with the following mods
Vf48
Turboback exhaust
Invidia Uppipe
GMS turbo inlet
K&N Typhoon
STI TMIC
Walbro 255
H.O.A 3-port
Cobb AP V2
It previously put down 280/280 on 93 octane @ 17.5 lbs of boost. with all of the previous mods except the aftermarket catback which is on there currently. So the problem is that after I decided to put the new catback on, I pulled the P0244 code (overboosted) some days later on a "spirited driving" trip. Knowing that this was a result of the catback, I figured I needed a retune. Unfortuantely, a few friends called me up to the track before I was able to get the retune in. However, Im proud to present you guys with these results. Keep in mind that because of this overboosting problem, I was not able to go WOT in 3rd and 4th gear. Id say I was somewhere in the 60-70% throttle range during those gears to keep the car from shutting off.
Results:
60'ft: 1.864
1/8 ET: 8.376
1/8 MPH: 84.07
1/4 ET: 13.0741!!!
1/4 MPH: 104.43

Plx let me know wat u guys think of the run. Any positive input would be greatly appreciated thanks!

I'm surprised by this as peak boost/fuel cut will usually take place at mid RPM and in high gear where you have the most load. I can floor my 4th gear from low RPM to redline but if I try it in 5th I hit fuel cut. At the strip I have no problem rowing through the gears because when I grab 5th I'm not making peak boost (and if I am it's not but for a split second.)

As for advice on your run, it's hard to tell what your car can/should run with the power it's making if you didn't have your foot down :P Your 60ft can use some work. A 1.86 is far from terrible but you should set your sights at a 1.6-1.7. That will bring your ET down.

Sorry lol. Correction, 84 mph not 95 LOL i wish. But its wierd, WOT in first and second are on spot, the boost pegs and holds like a champ, but as soon as i hit third itll start immediately overboosting. From wat ive told, all that needs to be done is adjust the wastegate duty cycles.

That would be lovely to crack mid 12's with the retune! Since I dont really know what setups similar to mine are capable of, its good to know that at least im close.

You should trap around 110 at least, of course after you get the overboosting thing fixed.

That's also fairly low boost. Slap an external wastegate on there, and boost 22psi untill redline

Going mid 12's is all on you. Get that 60ft down as far as physics will let you! Practise!!!

IIRC, the only reason the boost is so low is due to the fact that my stock injectors are somewhere in the high 90 % IDC range. Also, according to my main man Jorge from P&L, my STI TMIC is also out of its efficiency range.

Sounds about right. A bigger TMIC will grant more power with your 48 for sure. Also some racegas
