Hello guys, it's been awhile since i introduce myself. So i'm here again to seek some help in general regarding boost controller.
I just purchase and installed brand new latest GReddy profec boost controller ( installed and setting/tune done by professional tuner all the way from japan ) today.
I haven't had any experience with a boost controller before but i know that if you set it to the desire boost level it should stay/hold right?
Well after all tuning was done, i decided to test the boost controller. Lo boost setting is 1.0 bar or 14.5 psi hi boost setting is set to 1.3 bar or 18.8 psi. Looking at the boost controller graph setting my boost look kinda funny. Please look at the picture:
The first picture shows the lo boost setting and the graph have a spike and the drop down and slowly building up boost. I manage to get 1.13 bar or 16.4 psi. This is tested on road starting from 4 gear 2.5k rpm all the way to 7k rpm. ( my rpm limit is 7.5k)
Second picture is hi boost setting i manage to get 1.4 bar or 20.3 psi same gear as the above 4 gear from 2.5k wot till 7k. The graph also shows a spike then drop then slowly building boost.
Shouldn't the graph suppose to be rising and then have a constant/flat curve once it reach the desire/set boost?
What makes me tick off is that this was done by professional, heck done by some imported renowned tuner from japan and yet they fail to let me know during the dyno run.
Hope you guys can help me with this problem. Somebody gonna get a hurt real bad ( russel peter's dad voice ) tomorrow morning.
Here's a picture of my dyno result after they "tune/setting" my boost controller.
The before result was 240 ish whp then after they tune/set i manage to get 295 ish awhp. Every this is stock except for dp and tbe.
Cheers and have a nice day.
