Over Boost

I was up at Rockford Racecraft recently having my truck gone over to see what they thought of the truck and if there was any problems with it. Guy was great and spent some a lot of time answering all of my questions. He took it out for some data logging and discovered that it had an over boost condition that would shut the truck off. The stock guage goes way past 15. It has a stock turbo and he checked to make sure the waste gate was working properly and checked some other things and thought that maybe because of the facd the truck did not have a catalytic convertor that was causing the overboost condition. We couldn't do anything more that day. What do you think the easiest way to fix this overboost condition. Would a chip fix it? Would a manual boost controller be the cheapest fix? Your thoughts and ideas are appreciated.

Thanks, John

Re: Over Boost

Install cat, go to external wastegate setup, port the stock wastegate on turbo, or If you go with a 3bar chip and 3bar map sensor then it wouldn't be concidered "overboost" because most all 3bar chips have that flag removed and with a chip programed to read 3bar instead of two it would supply the additional fuel for the higher boost (greater then 14.5lbs)..

Re: Over Boost

put back on the cat or run a boost controler. How much boost was it getting. Do go by the stock guage. My would max out even though I was running 12 lbs.

Re: Over Boost

I bought the truck without a cat, so I would have to buy a new one and have it installed so I don't know if that is the cheapest or easiest option. So am I getting this right, that if that is not an easy option that a chip or manual controller would be my best bet?

Boostedpimp, I read your suggestion and thought that was two options, exteral wastgate and mods or chip. Which would be the easiest and most cost effective? Thanks guys.

Re: Over Boost

With a manual boost controller, in a way you'll still be overboosting. It won't be the right way to do it. In reality you'll be setting your boost at like 12-13 and be overboosting up to 15 which will make it look normal. So in the future if you do more add ons then it will need to be compensated everytime.

Just put a cat on and it will be right. Like $80 for a nice cat and $40-50 bucks to have it welded on by a muffler shop. :2cents:
