Hey there! For your 1993 Chevy 2500 6.5 turbo diesel, consider upgrading the wastegate actuator. It can improve boost control and enhance performance significantly!

That’s a great tip! I’ve also heard that a performance chip can work wonders for power and efficiency. Anyone tested that?

A performance chip is definitely worth considering! I had a friend install one and he noticed a significant increase in both power and mpg.

Does anyone know which brand is the best? I’ve seen several options but am a bit lost.

I’ve had success with the Banks Power products. They really know how to extract performance from these engines!

Performance upgrades are great, but don’t forget about maintenance! Regular oil changes and a good fuel filter can make a big difference too!

8

Totally agree! It’s the small things that can keep your truck running smoothly while you upgrade.

I think a turbo upgrade could also be beneficial. Has anyone tried switching to a larger turbo? What were the results?

10

Larger turbos can help, but they might require some other modifications for proper tuning. Just a heads up!

Hey, we all want the best performance, but let’s not forget-how many times have we heard “just get a bigger turbo”? Sometimes less is more!

I totally get it! The 1993 Chevy 2500 with the 6.5 Turbo Diesel has some quirks. One common issue is the fuel pump. Definitely check for fuel flow problems if you notice performance issues.

Absolutely! And don’t forget to inspect the PMD (Pump Motor Driver). It’s notorious for overheating, which can lead to starting problems.

Great point about the PMD, imosley! Also, check the intercooler for leaks. I had a friend who lost power just because of a small crack.

Good one! I’m also dealing with a rough idle. Could that be related to injectors? Any advice on troubleshooting?

16

Definitely! Poor idle can often mean clogged injectors or even air leaks in the intake system. Have you checked for error codes? They can give you insights into what’s happening.

That’s what I’m planning next! If I find anything, I’ll post it here. Thanks for the suggestion!

You might also want to look at your glow plugs. If they’re not functioning well, it can cause hard starts, especially in colder weather.

That’s a good tip! Sometimes, people forget the basics. Honestly, I’ve found that the simplest fixes can solve the biggest headaches.

True! Just the other day, my truck acted up and it was as simple as a loose battery cable! Always check the small stuff first.
