I'm seriously considering getting the TST power kit (#11 version) and AFC spring kit. Anyone here running these? Based on other sites and searching around a bit, I've only found happy campers... Seems like a very reasonably priced way to get considerably more power coupled with better overall mileage and controlled EGTs.

 

Aw shucks... nobody?

 

you can actualy grind that fuel plate yourself if your handy with a grinder. however the kits from tst are good for some nice power upgrades.

 

i'm running the TST #5 and AFC spring... really woke up the truck.

 

What truck do you have? (Fill out your signature line in your profile so we can all see...)

According to the TST site's chart, the #11 is about as far as I can go with my stock clutch:

 

ha, guess i should check the signature button...

 

I understand the fuel plate, but what exactly does the spring do?

 

the TST spring is softer than the OEM spring. basically it alows the pump to add fuel faster. the truck feels like it revs more freely now.
