boost control problems

[black cat]

i put an up graded turbo on my ty not a huge one and a 3 in exhaust. without the factory boost controller it hit arond 8-9 psi pretty consistently. with the factory controller on it keeps the boost arond 12-13 psi if i just roll in with the gas and also it ramps up must faster.when i drive at 40 50 mph and floor it the boost ramps way past 16 within 1 sec and the truck hits boost cut. am i simply in for a boost controller because the factory ecu just can,t keep it under controll i do have a little bigger lines from the turbo to controller to the waste gate thks

Just curious but are you also feeding your hungry engine w/ more fuel for the larger turbo?? might be some of your issue

Re: boost control problems

What wastegate are you using?

Good point

Try adjusting the wastegate
Try using a boostvalve to isolate the spike.
Change the boost ramp up % using code 59
External Wastegate
One of these methods should fix it

Re: boost control problems

i have a wide band on it and at 12 -13 lbs its at 11.7-11.8 but i can,t take engine past 4000 rpm because it hits boost cut. no knock retard with 94 octane. i take it easy with the solenoid on it because it unpredictable from one boost to the next. it just adds a lot more grunt with it hooked up. i also have the ostrich and the burner and 50 lb inj but i din,t see a file on code 59 .i,ve only been on the sight a couple of times. would there be a turn key file somewhere.ha ha

Re: boost control problems

it has an internal gate. i would put an external on but where is a good spot to put it with stock manifold setup. i have turbonetics on my s 10 and it is flawless.
