How many lbs. of boost @ launch?

How much boost are you guys hitting when launching? I am only building a few pounds when I'm bouncing off the 5,000 rpm 2step. And I am holding it at the line. Is this normal? Can this be changed after I get the car flashed? It's also dropping off as soon as the clutch is fully released which is killing my 60 ft time.

How? From the flash and mods? I'm basically stock. Should I only be boosting at 4 psi when launching? I can't get it to go higher.

Are your keeping the throttle floored or just holding it at 5000 with slight throttle? What 60ft times do you get?

Why would mine be so much lower? I'll just go ask the Mitsu dealership tomorrow... "Why aren't I boosting when I launch the car at 5 grand?" lol

ttt. Can someone answer why I'm not boosting as high off the line? Is that about normal for an unflashed IX?

Does the flash raise the boost at launch by just raising the rpm? If so how much so an IX expect at the 5K factory limit?

maybe your boost gauge is not correct? Take it to the track and look at your 60' times
