So I got my Car Dyno'd yesterday and...
Finally got the Apexi Neo all hooked up and tuned; Base line was at 184.13 HP and 186.03 Torque. After about 10 runs we got it to 202.45 HP and 219.55 Toruqe. Increase of +18.32 HP and +33.52 torque. I was pretty satisfied with the results and kept the current results. This is a GS300 w/ about 150xxx miles, intake, magnaflow mufflers w/ 2.25 piping all the way back. I had my heavy 20's on when I got it dyno'd also. So, what you guys think?

Nice! Based on a 20% drivetrain loss your car (225hp) bone stock would make around 180whp. Now with the mods you added (not incl the Apexi Neo) you gained about 5whp...and the tuning (addition of Apexi Neo) added another 18whp! Those are GREAT results!
I try to tell everyone that the Apexi Neo (or any other A/F tuner) is a GREAT mod addition for power. Obviously you get better results when you have an intake, exhaust, headers etc etc. If it were just installed on a bone stock car you would probably see only a 10whp gain.

yea I can feel quite a difference but its not like the fast n furious difference. car drives n sounds a lot better lik she jus got woken up. I took it for a test drive lastnight next thing I know I was at 85 mph. my check engine light did come on but after reading one of rock-a-lex threads I jus reset it n so far it hasn't came back on.
cocobun- that's the only graph I got

I got similar increases when I added the Neo on my GS4...the guy said my dyno was around 252whp and around 264wtq with just my K&N intake, Borla Exhaust and TM spark plugs. I added the Neo and I was then up to 267whp and 291wtq; +15whp and +27wtq...then I added the headers and had it retuned and went up to 282whp and 306wtq; another +15whp and 15wtq.
This is HANDS DOWN a GREAT mod...and you can KEEP TUNING IT! This is/was the ONLY reason that I was against buying the SRT intake kit because the SRT race ECU is not tunable for future mods.
Your results are great...you should be right around 255hp (crank)...so that's a rough gain of 30hp (crank)!

no I had low end loss when I added the intake n mufflers but with the neo I felt the low end pick up more. the car is quicker thru all the rpm range which I love bc it was really slugish before esp in the lower rpms

Well, that is the STRANGEST before and after dyno sheet I have ever seen. Looks like two completely different engines and the plotted blue lines (after) are nowhere close to matching what is indicated while the red lines are bizzare.
Baseline of 184hp/186tq is the red lines and the peak reading for both values are at about 5200rpm (torque and horsepower are always the same at 5252rpm) and from there BOTH numbers tank to MUCH lower readings with peak power at 5950rpm of only 160hp and peak torque at 5900rpm of under 140tq. There is NOTHING usual about the before dyno numbers and in fact seem completely incorrect. Peak torque should be around 4500rpm and peak power should be around 6000rpm. That said the actual numbers (NOT the shape or RPM points on the dyno sheet) are more or less what you would expect. Super strange.
Now, the blue lines which are SUPPOSED to be the after readings are NOWHERE close to the stated after numbers. In fact the blue lines are right in line with a CORRECT chart for the BEFORE numbers with an indicated peak power of 186hp at 5800rpm and peak torque of 180tq at 4800rpm.
While your tuning seems to have been successful based on the typed power numbers the dyno chart shown is worthless and contradictory.
