I have a 99 Silverado with headers, exhausted and intake. It's a dog off the line until 2200-2500 it will start to pick up. What can I do to get rid of it, I now a stall will help but what other things can I do? I'm also getting a Nelson tune in about a week and cutting my cats because they are filled with crap. Will that help me at all?

 

A big turbo with a big enough stall, although that wouldn't help off the line it would still be fun.

 

gears

 

gears will help out a good bit, although a stall around 3k would make a huge difference, honestly its the most noticable mod i've done on my truck and others will agree. I mean it goes from feeling like a dog on the low end to feeling like a dog on the top end! which means its time for a cam,which is in the future plans.

 

i dont know about the pi or tci, but i loved my yanktt3000, has a good str and woke my truck up at lower engine speeds, only downfall is the price and customer service. i know youre looking for other options but i think this would be the best for it. if your cats are plugged it would run like ****, no power bad fuel economy, possible check engine light,. nelson tune will help out and if he delets tq management you will feel a difference.

 

A stall is probably the best bang for the buck you can do to your truck. If you can find anyone that has a stall to take you for a ride you will have to have one.

 

My Yank TT3000 works great! The price is a bit higher, but I believe you get what you pay for. As far as customer service goes, I never really needed any customer service, as I bought mine from Tbryne and I never had any problems. I've also heard that they are under new management and customer service has greatly improved since they were have their issues before. I think dollar for dollar the converter is the best mod out there. You can spend $350 to $400 on a cat-back, and another $250 or so on a cold air intake, and still not have the same performance gain as with the converter.

 

Stall, tune, nitrous. Not necessarily in that order. Those are the best bang for the buck IMHO.
