[Topless in Cali]

How did you get around the spare tire and exhaust? or was there just enough room between them for the battery? Could you post a pic from underneath the car so we can see it's location in relation to them.
UCP:
As far track testing, there are soooo many variables that go into actually putting the power down, I doubt you could really pin down any single performance upgrade that would give you significantlly better track times, other than a turbo upgrade, or going from n/a to super or turbo charged. Driver, track temp, wind speed, tire temp, etc., all these things connot be exactly duplicated from run to run on the same car before and after doing a single modification, but it can be duplicated in a garage on a dyno, resulting in better #'s. That being said, the UCP in conjunction with other mods can result in better real world performance. I know after adding Adam's pipe I had to turn the manual boost contoller down because boost came up much quicker and it caused a spike! IMO, that means, at a minimum, the hard pipe increases the efficency of our little turbos. That may not result in a better 1/4 mile eta., but most of our driving isn't done at the track.
