Thomas we picked a really good day to dyno your car 
. The temp in that dyno room was 107 degree. It only took 3 runs to dial in the right AFR. First run it was a little too rich. So I took some fuel out and some meth/water also. It's not done yet. The headers are coming on tomorrow. BTW, That meth kit works very well.

Rev limiter. I had my eyes on the boost and AFR gauges. It pulls strong all the way to redline. AFR stays rock solid at 11:1 with meth/water injection in the mix. People said meth/water tuning should be around 12:1 and I don't believe in that. I want to leave some room for safety!
The split second does an excellent job for partial throttle. Since our stock computer like to stay in the 14.7 range, Split second modified 02 sensors signal so we won't have any problem with partial throttle tuning.

JPI Headers
We were installing the JPI headers today. Passenger's side fits without any problem. We ran into some issues with the driver's side, The steering shaft is very close our header. Keep this in mind, We fab these headers from the stock units. The longer runner would have to move 1/4 of an inch back for it to clear. Some changes move have to make to the main jig that we built.
A/C compressor would have to remove for installation on driver's side header. While you are at it remove that oil filter and the header will slide right out.
Transmission dip stick would have to come off. The 12mm bolt sit in a very hard to reach spot.
Oil dip stick coming off also.
Since the exhuast nut stuck on there real quick. We don't have any choice but cut that stock manifold.

Plasma cutter do come in handy
Stock Vs JPI headers
Here is the problem that we ran into. Like I said, we shifted the headers 1/4 of an inch toward the back.
I will upload the videos later tonight.
