Mods are in my signature. MPI tuner and rear mount (not that it matters) were not installed.

red pull- stock boost- 3rd gear- 165.5whp/167wtq
green pull- stock boost- 4th gear- 168whp/170.4wtq
blue pull- ~7psi- 3rd gear- 179.5whp/179.1wtq


this was done on a dynojet.

Get that mpi in and fix the afr's. Not bad none the less. You planning on keeping it at stock boost-7psi? I would raise it alittle bit, you have the supporting mods.

im gonna raise it up to 10psi. im just conservative and i thought it would be a shame if i blew the car up on the dyno and have ems about to go in.
 
Really surprised, with your mods I would figure that you'd be up a bit more HP. I have very similar mods to you but I'm running it at 9psi and am very happy so far though I have not had it dyno'ed.

here is an updated dyno. my current setup is in my signature. the mpi tuner is setup the kooldino way.
There are 2 pulls:
1) 6 psi
2) spike to 10.5 psi and taper down to 8 psi (i cant get the profec to hold to save my life)


1) 177.82 whp 190.29 wtq
2) 203.68 whp 208.98 wtq

Looks like the tq jumped up a bit from the first dyno at 6psi. Hows the 10psi feel. Are those your two boost levels on the street for high and low boost?

the ten psi feels real strong. i just wish i could keep it to hold 10 consistently. i just run around on the high boost setting and keep my foot out of it if i want low boost. i got the baseline map (stock boost) so i will have a low psi map for breaking my built block in during the upcoming months.
