Something wrong with my truck?

[2003kingranch]

so i have a 2003 f-250 king ranch with of course a 6.0l. this is my first 6.0 and this thing hauls ***!!!!! compared to a 7.3l. anyway i put a 4" mbrp turbo back on (no cat) a SCT X3 tuner tuned by mkm customs. and a K&N intake. thats it for now

anyway when start getting into it and stomp on it. and when it gets up to about 2600-2800 rpm, it fells like im spraying it. its like you lit a match under its ***. im hopefully going to make a video tomorrow. sooo is this normal. i am thinking it might just be the vgt turbo opening all the way up and making a ton of boost

any ideas guys?

Does it do it when returned to stock? Depending on the custom tune, some have what is known as a "slingshot effect".

It's common with al custom tunes. It has three stages basicallly. Normal driving, 3/4 throttle, and full throttle. I call it the "light switch effect."

doesnt do it stock. just on my hottest tune which is 105hp
