! Cat, Overboost & EBC

[jamnut]

I've been searching pretty hard & can't come up with a final answer to this question.

Can you control Overboost caused by deleting your cat with an Electronic Boost Controller? This is for a stock turbo. I realize that overboost can be caused by the small Wastegate flapper on the stock turbo's, but I was wondering if an EBC could help cure this?

It would only work if you set the EBC for lower boost level. If your max boost is 15psi (close to stock) i would set it at 12, it will/may spike to 15 and end up around 12 most of the time. It might help but it will not elimate the small wastegate problem.

these trucks are too self-dependant to give you a clear answer. One truck might be fine, another might overboost. The only way to tell if this WILL work for you is to try it.

I just may try it. I've got an ATR downpipe & Tial WG sitting at the house right now, I just wasn't going to install that stuff until I got my new Turbo & Boost controller. So I figured that I would just get the boost controller now & play with it & the stock Turbo, until I get the $ to get the new Turbo I wanted.

If you havnt removed your cat yet, I'd say you'd be lucky if it works, the odds are easily stacked against one being able to use the stock wastegate with no cat. If it is currently overboosting, changing the controller isnt going to change physics inside your turbo.
