It is a beautiful truck no doubt, the details you have put into it are nothing short of a work of art....But do you ever race it or use it..it is always clean and purdy. Track times?? I mean no disrespect here Richard but most of us work the crap outa our trucks daily and play on the weekends with them. Mine is as slow as it gets but I still have fun with it.
It has been down the track....112+ mph trap speeds.
We have very recently come across some issues with tuning on 03/04 motors that my truck is a victim of also.
There's something causing a defuel and nobody has any idea what it is or how to fix it.
My truck and about 20 others to date that have been scaned are maxing out at 68% engine load. Mine will run up to 68% then defuel horrily. By the time I hit 100 mph I'm back down to 35% load.
We are also hitting a wall on boost...62psi no matter how it's fooled.
This week I had parts machined to run a regulator between the manifold and MAP sensor to physically limit it to 36psi thinking it was a MAP based issue....it isn't. We scanned it Friday night and it made no change to engine load percentages.
Once we get a handle on what's going on and how to fix it...I'll be down the track again but right now I don't see the point.
Max load is 120%...no need to run at 68%....why try to run a number when the truck isn't right ?
As it is...I drive the truck every day...it's no garage queen. This weekend I drove it from Chicago to Martin, Michigan to watch my friends that run ADRL then went from there to Indy then back to Chicago last night. It runs fine...just not 100% fine.
112 mph at 68% load....7560 lbs ? That tells me there's a LOT left on the table. We just can't quite reach the table yet.
