First top mount single turbo 370Z

My runs were as follows:
On pump gas hitting 11.5-12.1 psi
1) launched around 3.5k rpms bogged and dead hooked 2.00 60' 12.13 @ 120.0mph
2) launched around 4.5k rpms bogged and dead hooked 1.88 60' 11.85 @ 119.6mph
3) launched around 5k rpms spun 1.99 60' 12.61 @ 118.3mph
I put in 3 gallons of 100 octane
4) turn the boost up and saw 13.1psi launched around 4.5k rpms and spun bad 2.10 60' 12.15 @ 119.9
The car started making a ticking noise. It sounds like it's coming from the top of the motor. A few people said it sounded like timing chain slap. They also said it's a common noise for the VQ. I'm not too familiar with engine noises, other than detonation. I figured it ran fine on the last run. I just put in race gas and temps were dropping. I wanted to run again.
5) did a big burnout. Then they stop the lane for a minute. Then I didn't have time to do another burnout. Turned the boost up again and saw 15.1psi. Launched around 4.5k and spun bad again. 2.08 60' 12.09 @ 121.7mph. Car felt like it was HAULING. I think it would have been good for a 11.6 @ 123mph, based on every .10 off the 60' is roughly .20 off the ET.

It was 1am and my friends were ready to leave. I wish I could have ran a few mores times. On the way home, I wanted to do a 15psi pull and let my passenger feel it. Did a 3rd gear pull...felt great! Hit 4th and something felt wrong. It wouldn't boost anymore. Car went into limp mode and I couldn't shift over 2500 rpms. With a 70mph speed limit most of the way home, I couldn't go over 60mph...made for a long ride home. It's acting the same way it did when I found out Lutz had cut 2 of my MAF wires. I'm hoping my wiring came undone...easy fix. I didn't solder them last time because it was too late when I figured out the problem and just wanted to go to bed. I'll hook up the Cipher later today and check the voltage.

Yeah, you missed out man. I met Tristan and Steve? With the white Nismo.
Good to finally meet you, Mike. Car sounded nasty when you left.
