Taking the plunge with a blower!

WHOO-HOOOO!! I finally got it! This morning I picked it up at Minneapolis and drove it home to Omaha. At the shop, he showed me the 5 tunes it has. One for 91, one for bad gas, one for valet (4400RPM max), one for not starting, and stock. Interestingly, it is changed with the cruise control.
Drove South getting familiar with it. Power pickes up at 3500RPM, and the pot is at full-boil at about 4000.
You remember the pre-tune dyno was 215. I drove a new 370z the week befor I dropped mine off, and it didn't seem any quicker. It seemed the same as my G. Post-tune dyno was 351. I feels loads faster. Punching it from a stop the front end lifts up on the suspension! Pretty cool. I use the paddle shifters exclusively when riding hard.
The oil cooler kept everything 190-210 throughout, and the tranny cooler kept the ATF 118-140.
Issues? Well, a few small ones. The boost gauge reads zero all the time. When I push the plug in it reboots. I'll have to trace the wires. All these gauges are lying on my dash, because I'm still figuring out how I want to install them.
The miles to empty gauge is now wildly optimistic. After a fillup, is says I have 550 mile until empty. The fual gauge seems to be OK. All I can figure out is that the ECU thinks it has the old injectors, and calculates fuel consumption via pulse width. These are not working as hard. The ECU doesn't know it now has "Big Gulp" injectors.
The outside temp is really high now too. There are 3 new radiators (intercooler, engine oil, and tranny oil) as well as the blower stuffed under the hood. The thermocouple must be near one of these.
The suspension really isn't up to these shenanigans. It has too much body roll for quick lane changes at high speeds. My sway bars are all ready to be installed, and I think that will fix it. I really don't want heavier springs.
Have any other forced induction guys noticed issues with the distance to empty computer or outside temp? I'd be interested to know.
One other cool thing you can do for fun. If your put it into valet mode in neutral and punch it, it goes to 4400 RPM and cuts out briefly and will repeat this indefinitely. It sounds like the is a freakin' unholy beast under the hod with the blower whine and aftermarket exhaust. This is gonna be fun when some rube wants to try me at a stoplight. You definitely know some big work has been done under the hood!
I'll post more when I get it more sorted out!
HAVE FUN!

Awesome! That Intake setup is pretty clever, I can't help wondering if a normal intercooler setup would net more or less power on this car, but I love the way they did it with less piping

I wonder how much HP it has. Their dyno is really low. It was 215 preop and 351 postop on their dyno. That's about a 62% increase. If I started out at 327 at the crank, that increase means about 530 at the crank. I don't know. Maybe. It pulls quite a bit harder than an M56 that I drove. They said its at 7psi. I guess I can dream. Can any other people who have used a dyno take a guess at what it might really be? I don't think I'll take it to a dyno for fear of being disappointed. I'd have to drive 3 hours to the nearest AWD dyno anyways. If I had a stick I would add water injection. It's relatively easy. I don't believe I want to risk trashing the tranny though. As it is, it is plenty freakin' quick. I don't know how people don't crash that 707HP Dodge.

Nice write up man glad you finally got it back. I remember how I was too!!
Buy a boost gauge. You should be seeing at least 8 PSI. Stock kit is set for 8 PSI. All tho I saw 9 PSI
