EBC holds same BOOST EVERY GEAR ?

Hey Guys I am just wondering if BOOST controllers are suppose to hold the SAME BOOST every single gear. Because me e01 will not hold the same boost for 1st and 3rd gear. If i set my first gear to be 17psi then my 3rd 4th gear will be 19 psi and if I set first gear to 19 3rd 4th gear will be 21 22 . Is this normal for Boost controllers ??? I never had a turbo car and this is my first time using boost controller.

Boost is based on Load you can't load up the turbo in 1 throw 3rd like you can on 4th and 5th.

Set your peak boost in 4th.

Also don't forget that a turbo runs best on it's peak effcenty So you will have a peak boost that will tapper off.

So its normal to have Lower Boost on 1st 2nd gear and higher boost on 3rd 4th 5th gear. Because I keep hearing people saying 19 psi to red in every gear and I just dont understand how is that possible.

It becomes possible with a full turbo back exhaust.

Personally speaking, I dont like setting it up to taper at all - I prefer it hit peak boost and remain there to redline, but its all about different tuning methodologies, the type of gas you get, etc etc.

I can't hold peak boost in first or second gear with a mbc and 3" exhaust.

I also wish I could hold peak boost, but on the Evo no matter what you do the boost always drops about 3psi in every gear.

For the people that can hit 19 psi all the way to redline every GEAR please share your experience with us. Is it somehting that we are missing like a BOV INTAKE or EXhaust let us know.

On a small turbo it would make sense. Why would you want the stocker to run all the way to red line?
