220hp on a mustang dyno=?

[TurboDSMer]

I was with my friend last night and we went to this guys shop that we know and used his mustang dynomometer. By the end of the session my friends numbers were 220hp and i forget the torque but it was very close to 220 as well maybe 210. any way the guy told us that it comes out to be 253 at the wheels, but that doesn't sound right to me becasue of all the mods he has done. They are as followed:

-Evo3 16g
-injen intake
-VPE O2 housing with tial 38mm
-Apexi O2 back
-6 bolt with perfect compression(165)
-Act flywheel and clutch
-750cc
-255lph
-dsmLink
-SBR FMIC
-HKS SSQ
-SBR exhaust manifold
-running 22psi on 93

I want to know what you guys think or did the guy give us a wrong number? The car feels fast as f*ck but the numbers jsut aren't right to me. We did a baseline and it was 186 on the mustang not calculated. But the thing i don't understand is i have been in the car with my friend when he raced a Z06 previous to the dyno and he had the Z06 from 60-120 and by 130 he was slowly pulling on us. What do you guys think?

tuning is very important with our cars...

with that said... is the car tuned?

When I had similar mods running 20psi on pump gas and tuning with an S-AFC I laid down the numbers on the left on an AWD Mustang dyno. (I was trapping 110 at the time also)

yes the main purpose of last night was to tune the car. Aslo the baseline was 186 then we tuned it to 220.

My numbers were "untuned" there were just baseline runs, i'm sure I could have gained with some tuning.
