Mod list:
- L36 block 80 something thousand miles.
- L67 top swap with unknown miles on the heads. Never checked for flatness, cracks, or anything else. Probably not good.
- gen III blower with a mildly ported outlet. I know... Gains are found on the inlet, not outlet.
- L67 TB with a mild port, that magically hasn't affected the MAF table much. Did a bad job most likely. Working on another.
- Gen III WBS 2.25" intercooler. Too tall, blower and fuel rail eat the hood yet I'm stock ride height, no spacers.
- Yella Terra 1.9 RR's with L76 springs/LS1 retainers. Great mod. Didn't feel any difference at all. Drives exactly the same.
- Speed daddy headers with a 3" non-high flow cat welded in. Leaky speed daddy flex still in place. AEM wideband is about 6 inches after this leak. Good idea right? At least its on the top half of the pipe.
- Maremont "performance" 2.25" crush bent to 1 7/8ths inch crush bent catback. Very quiet. Sure its hurting them performance numbers.
- Short ram intake with a very oversized air filter. Going from old small K&N to new oversized amsoil filter (dealer was terrible) resulted in PCM adding another 2% fuel at WOT. Driver foglight has ducting running into the engine bay right beside the air filter.
- 3.4/3.6 ZZP MPS Boost is good.
For those who REALLY care: 180 t-stat, TR6 spark plugs side gapped at 0.045".
Saw an HPT for cheap, decided it would be a good way to spend spare time.
Car has been tuned by Will previously.
Had it tuned to 11.0 AFR on the 3.4 pulley, 16* of timing, not much knock to worry about.
After a week the car would add fuel at WOT bringing it down to 10.2 AFR.
Had it touched up. Still occurred.
Added half a percent to the below 5000 Hz MAF table and it seems to be doing just fine in that regard.
Next step was trying leaner. Got it to 11.3. Still experiencing KR at 16* solid advance.
Tried a 3.6 pulley and 17* advance with the same results.
Went back to Wills 7000 Hz + maf settings for a solid 11:1 AFR and the 3.4 pulley.
tried 15 -> 16 -> 17* timing advance. Still didn't like it, the 15 helped out in the mid/high 4000's rpm. Yet the 17 up top the motor didn't like at all.
Threw the 3.6 back on with 16 -> 17 -> 18 timing advance.
Heres some of that fun:

Note I can't seem to get the WB AFR to log properly. Sometimes its bang on, others its not.
