Dyno soon, cooling advice please :-)

[LS3pwrdBuffalo]

Hey guys getting ready to do a nice bolt on setup (headers, exhaust, 2.5 upper, id850s, rotofab, 160 stat, ect). Kinda running shy on money atm especially with vacation around the corner. My question is can you think of any reason i'd need to have the hx, reservoir, chiller installed for the dyno? Time isn't an issue with my tuner so if we need extra cool down time its no problem but basically i'm wanting to get all these parts on as im running out of time, get the tune done, and then in the next couple months get the cooling/efficiency taken care of. I'm pretty sure i'll be fine but just wanting to make sure i'm not looking over some important need to have it done beforehand. Thanks guys :-)
