What Next? Headers, TC, other ideas?
Tune???
Someone please explain to me what the safc or neo actually do. After all the experience ive had with tuning my 430 after I put the turbo on, I just can't seem to grasp what anyone of those controllers actually do. Do they intercept the crank signal or injectors, does it alter the intake air temp. readings, does it suppress knock sensor signals? Once anyone installs higher flowing bolt ons like cold air intake or headers, the computer is automatically going to detect the increase in airflow and adjust accordingly to an extent.

These units do not control O2 or cam/crank sensors (for timing). Since its a simple unit it works very well for almost any car but it is typically only used for NA or very low boost applications (under 4lbs).
I gained 20whp and about 22wtq on back to back dyno sessions when my car was NA. My final dyno was approx 282whp and around 306wtq IIRC on stock 16" wheels. My 19" wheels slowed me down a bit with my 275's but with a better tune and I did a little lower at 275whp. All runs were done on a "heartbreaker" Dynodynamics dyno (like a mustang dyno). For the record, the stock ECU NEVER overrode my AFC tune...it stayed the same since my dyno before.
Seriously...keep it.
I am regretting selling mine to the extent I contacted the buyer of mine in hopes I could buy it back with my custom Boomslang harness; no dice.
I could have gotten away with 4PSI on my SC kit and literally saved thousands! But I want the 8+ PSI that it's calling for. Since selling I've bought the FIC8 for $500 (if tuned properly I actually heard it was a great unit), new Boomslang harness for $350, various tuning and diagnostics at approx $1200. Nightmare. Trying to square up this Thursday; fingers crossed.
Bottom line, keep the Neo...its a great little unit.

Tune???
Ok so heres the deal. when I was doing my build, I ran my air fuel ratio gauge with wideband sensor for about three months and found that idle or cruising was at 14.7 afr. when I would go wide open throttle and the computer would go into open loop fuel mapping my afr would hold steady at 12.5. so the question is what afr does the safc or neo put the afr at at wide open throttle or cruising. that is the question.

K&N Intake and L-Tuned Exhaust Dyno Charts
Here are the charts from my first tune at Dyno Comp, with only my K&N intake and L-Tuned Exhaust.
Debating on picking up a Tanabe exhaust before my next tune. Still undecided if it's worth the sound. HP gains won't be that noticeable.

i think you can fabricate a better exhaust much cheaper and probably better sounding... Yea its Tanabe but it almost $1000... Topspeed pro with there y pipe on the V8 is impressive IMO... I have the Y-pipe into BlitzNurSpec.

I agree. I have the same y-pipe but going to a Borla, but about to be switched to an HKS... sounds great with the Borla as-is.
Between the sound they are very similar.. even though the Tanabe removes the resonators in their design. Looks wise\ tips the Tanabe hands down. I'm sure it flows better too.
On to the point of a custom exhaust.
When i was installing the Tanabe I had the Borla's removed and was just running the factory Y pipe and resonators, no mufflers. MAN did our V8 sound sweet! I drove it like that for a couple of days an everyone asked what i had under the hood as it sounded sooo sweet.. had an amazing idle and growl when you got on it. Maybe this summer I will look into running straight pipes from the resonators back with some nice tips.. it sounded that good!
I have had the Borla's and now the full Tanabe touring.

the tips on the Tanabe exhaust are by the far the best IMO...
