Auto, BPU, couldn't go above 16 psi on the dyno because I was on shitty plugs, so I should be putting down ~400 or so at 18+ psi (good gas + new plugs in).

Couple concerns:
1) Wouldn't pull until 6.8k. I think it was because overdrive was on? Trac fuse WAS pulled.
2) Where's the little "spike" where the second turbo kicks in? Is the sequential system not working correctly? Car was in temporary TTC when I got it and I put it back in sequential
3) What can I do to prevent all that power from dropping off near redline?

Thanks,
Marc

1) I dont know, I dont have an auto
2) Which spike are you talking about specifically? At 4k is where the second turbo is coming online. Is that what you are talking about?
3) You are running Really rich after 6k. Your a/f ratio is in the 10's which is pig rich. Your a/f ratios are kind of all over the place. It looks like your car is OBD1 because it runs kind of lean until 6k and then goes extremely rich. If you tuned the a/f you would pick up some power and more top end.

Just my $.02

Do the spring mod and you'll pick up 20+whp. Also, put the car in drive and turn overdrive off with the button on the stick.

Other then that good numbers for 16psi. For comparison I made 405whp at 20psi dropping to 16psi. Did the spring mod and made 425whp at 22psi dropping to 18psi. I had just the front mount and cam gear at the time.

Mine put down 380whp but i had to let off at 5200 :-( (didnt start the pull until 4400 BTW)
My a/f was at a dangerous 14.1+, so adding more fuel so it actually has something to burn will surely pick up more than a few ponies, as this was just too lean. My mods are as follows
Custom top/bottom fmic(gained 3 psi and 300rpms less lag with this IC)
HKS superdragger
rmm dp
bleeder t
hks filter
18psi

I have an s-afc, and will be putting that in asap. Also will be puttin on my fuel system for the upcoming 72gtq kit. I think my fuel filter needs changing is why it was so lean. With my configuration right now at 21psi , if the a/f was at or near 11:1, i think i would hit right at 420whp. Everyone that rides in my car says its a freak of an auto car. One more thing, my longblock has 180,XXX miles
