Woops thanks for pointing that out... the 83's were the ones I was actually looking for there.

And changing over to SD isn't something I'd recommend without your tuner there. Drive it on the trailer in 1 BAR Maf mode & change it when you get there. Following the HPT instructions makes it pretty straight forward, but it won't run worth a crap when you fire it up the 1st time!
As for what else you'll need, I have the Nasty Stage III fuel system & the fuel pressure is dead solid. (twin Racetronix pumps built by Lonnie + big lines & a regulator) Give Nate a call....

This will help a little, found this today.

I should be able to input all the information via laptop and HP tuners to fire my car up at least and idle it out of the garage on/off the trailer. Rather than pull MAF, swap injectors, and ETC when arriving at the dyno.

HP tuners offers a 2 BAR SD for 98s, I didnt have a lot of luck with it when it first came out a few years ago but I also didnt spend a lot of time with it.
You can also do a fake 2 BAR where you half the VE tables and anything else to do with the MAP, it works but you have to disable BARO updates so big weather/elevation changes will require tweaking.
Unfortunately 98s are all alone and a lot of tuners dont bother with them..

There is no problem running SD on a 98 n/a, its doing a 2 or 3 BAR thats the problem.

When you goto SD without a custom OS though you are stuck with the tiny Secondary VE. So right off you are going to be halving a table that you just halved by putting the car in SD without the custom OS. Also since the sensors don't even read to the 'floor' of the secondary table, your resolution really will be unacceptable.
