How much boost do you make?
Anyone check how much boost you make. Just got the dashdaq and it shows 35 psi. Anyone know how to adjust that to actual boost instead of map psi which is atm press + boost? IAT fluctuates a lot. At idle it can go to 170F. If you hit the gas it drops 20-30F due to the volume of air flowing. Cruising at 70mph with outside temps at 70*F it is around 120*F. Throttle angle has a lot to do with IATs. Timing retards a lot if you floor it, can go to 0*TDC, but when decelerating it is -30TDC, normal?

Somehow I don't think you are getting 37 psi. If that's a normal MAP reading (like mentioned above) you are getting 22.3 psi (which is still a decent amount of boost).
Most turbo dragstrip queens (Supras, the bigger DSMs/EVOs, RX7s, etc) are very rarely running above 40psi regularly, and that's on a HUGE (we are talking about a turbine the size of a small dog) turbo, with engines that have been built to the teeth, filled blocks, wheelie bars, etc. and COMPLETE (standalone) air/fuel management systems. The more brutal ones run higher numbers but they're rebuilding motors constantly.
37psi (actual boost) in your 600 would kill that motor in a heartbeat.

Yeah I know, I am trying to find out how to make the dashdaq read boost only by subtracting 14.7. Anyone know how to do it? Otherwise it is cool to see it hit the 30s.
