Evo 8 /w Buschur 2.0L Stock turbo BC272 Magnus v3 E85 31psi

Steve's car took a very long time to get right sorting through all the bugs it had, but we got rid of every single last bug from fuel pump issues, to FPR issues, to boost leaks, to ignition issues, and the list goes on and on.

Steve listened to me the entire time working out all the bugs and kinks and all his work paid off. At the same time he learned a great deal about his vehicle also from me helping him diagnose his issues for him.

I would of liked to push the car just a little harder, but Steve was already very happy with the car and said he was surprised it even performs the way it does, so we let it go as is.

If the car had some better cams, like a S1 or S2 I believe it would make a lot more power yet. Another 20whp atleast or so.

I feel the sheetmetal intake has helped it uptop, but down low it suffered a little.

Temps were around 70F when tuning.

The mods are:

Buschur 2.0L Wiseco HD 10.5:1 / k1 V2 rods
Buschur Stage 3 Head / kiggly beehive springs and ti retainers
BC 272 cams
Spark Tech non CDI COP
Magnus V3 sheet metal intake manifold
Buschur double pumper
FIC 2150cc injectors (44% IDC)
Buschur downpipe
Buschur Race FMIC
Buschur ported and coated O2 housing
LiteSpec titanium exhaust with MAP test pipe
Injen modified intake
Injen licp
ETS short route uicp
Tial Q BOV (vent to atmosphere)
Tephra v7 speed density /w hybrid boost

Graph and a few pics of the car:

The car feels great! It's awesome to finally see it running correctly and to actually be able to put down some power.
I really didn't expect to see over 380awhp out of this turbo, I was honestly surprised at how hard Tom got the car to pull and don't think it could've been done better by anyone else.

I'm glad you are happy Steve. I'm also glad we were able to diagnose and troubleshoot every issue now that you can enjoy your car the way it is supposed to drive and boost.

Looking forward to retuning it once you add a bigger turbo.
