Ok I just got my HP Tuners, its hooked up. I have a procharged 408 with a D1SC. Car is a 2000 Trans Am. I dont see a 2.5 bar MAP SD tune opption in HP Tuners. I plan to upgrade to an F1 in a couple years. Which MAP SD tune should I spend my credits on and what model # is the map sensor I need to go with?

I had planned on doing a 2.5bar tune but well its not giving me the choice. I have 2 credits left so the decision needs to be the right one.
Thanks in advance folks

Just go ahead and get a 3 bar so you don't have to spend money again.

Once you buy the HPTuners custom OS, you should be able to switch between 1 bar Custom OS, 2bar, and 3bar without using anymore credits.

What he said. If its a Gen IV you can do the 2.5 map sensor but not on the Gen III. So like the other guy said go ahead and get a 3 bar map sensor if you plan on running more than 15psi

Actually folks...I made my jump on the 2bar upgrade and it unlocked all upgrades.
