Shane checked the timing marks and everything looked Ok, he swapped out several of my sensors, spark plugs, etc

The only thing we didn't do was the knock sensor itself. (maybe next time, as I have a spare)

Coming in with everything Zero'd at 20psi. 266whp@20psi with some rediculiously rich A/R (like 9:1) to rich to gas fumes were burning my eyes :headache:

After Next run Shane got it to around 290whp.

All in all I think we did 4 runs at 20psi. Top number was like 303whp but knocked to much so we had to shut it down early with out finishing the run.

After that was when we lowered the boost. and started swapping parts, etc.

Funny thing was when we lowered the boost we made just about the same HP as 20psi. But were still knocking (only now at 3 counts instead of like 5+)

In the end we gave up at like 1am, with a 10.5:1 A/R (at it's best A/R) 17psi and almost no knock (.04) making 280ish whp. (as you can see we didn't even start to get into a normal tuned A/R range)

We hopefully narrowed my problems down to 2 things:
-Bad Gas
-Bad knock sensor

I'm trying to schedual a time to get back on the dyno but this time with C-16 that way I know it's not the gas. and I'll bring my spare knock sensor. Plus another 02 sensor to replace the one that shane gave me.

Mine broke while trying to set the LTFT's. (wire broke right at the plug some how so there's no chance of fixing)

All and all it was a very long night. And I have to thank Shane, Moe, Tyler for helping me work on my car for so long that night. Plus the other 4 nights of running around getting parts to install my GTR FMIC and what not.

Sorry for the hastle Guys I really appreciate all the help and late nights you stayed and allowed me to work on my car.
