Low Boost Help-Frustrated
I posted over in the general forum because I thought I might be having an issue with my chip, not the case. Truck was running great up to a couple of days ago. Friday I get in and it is a gutless wonder with no power and boost no more than 9lbs.
I have read several forums trying to solve this. Many say it could be the back pressure sensor and line being clogged, many just remove the connection. I decided to remove the connection to see if this would change my situation. I let the truck warm up well and drove it around a bit with my exhaust temp getting up to about 475. I am now seeing boost up to about 16lbs max, much better but a far cry from the 25lbs I had before this started. If I pull the sensor and tube then reconnect the electrical will the computer see this and revert back to being normal or do you think I have a different issue like a wastegate problem.
Its a 2002 F250 7.3. I have an older chip (superchip gold bar) 80ho/100lbs torque. Borla exhaust, and a Volant sealed cold air intake system.
The engine purrs just not the power it had a few days ago. Even though this helped some it does not jump of the line nor pick up quick, but better with the sensor disconnected.
Really at a loss here and looking for some help, pics are god too. Oh and please don't tell me to get a new chip because what is in there is a POS. It's been a god chip and has served well.
Thank you all in advance.
