Enlighten me please

I have a 97 7.3L turbo diesel and I was wondering why does it feel like it's holding back when I step on the petal ?
Is it just old or do I need to get mods for it?
Is it the transmission?

Are you running gauges? What do u have for boost. And mods already? Exhaust? Intake?

Just added a K&N air filter for the moment
I don't have anything fancy yet

Get rid of that K&N.... it allows to large of particles thru and u will dust your compressor wheel on your turbo.

As for it holding back, is it just the laggy turbo it has

[T9X]

What would you recommend?
An new air take kit?
So get a new turbo?
Isn't there a device that holds the pressure more so you get more of a boost?

Do u have a stock replacement filter or a K&N cold air intake. If u have the CAI, go to riffraffdiesel and get their 6637 filter. I belive it will fit inside that intake. If u have a stock replacement put a stock filter back in. Or get a TYMAR intake from dale at TYMAR Performance. As for your holding back problem, b4 u go throwing money into it on mods when u may have an actual problem.

Take it to a shop (preferably a diesel shop) and have them run a full scan for codes and then a full report on engine vitals.

And for the devise that hold more boost, that is the wastegate mod for 99+ trucks.

6637 air filter a 3 inch down pipe remove cat and muffler really wakes the truck up

Does a CAI make a difference compared to the stock air filter housing?
I thought it might be codes because it is older and things do tend to wear out. I know my dads which is a newer model doesn't do what mine does. It just takes off. No mods either on it. I just wonder what could be different.

Also do diesels need a catalytic converter?

New vs. old. Hmmm, I wonder.
