Boost drop in higher gears?

[alundra]

The orange thing was replace by this: when i fitted my intercooler set up, i knew it was prone to break.

Tomorrow i'll set the desire boost in 4th gear, will know if in 2nd the boost is stable.

P.S: i checked the timing it's at 15°, warm condition.

Are you agree that in same rpm, i'll get the same amount of boost +/- 1psi?
