Just got my TST and will definetly want one of these boxes in the future. What are the advantages, disadvantags to these boxes. Which give the most hp, adjustability, low end power? Thanks.

 

The VA is good for towing, but does not work too well in combination with the TST according to some who have tried it.

Since the '03 EZ is not in-cab adjustable, I'm going with an MP8. If you only need a couple of settings, the EZ is the way to go. The MP8 is infinitely adjustable.

From what I understand, the MP8 fuels harder as well. I think it's also the box that boost fools on the positive side (during low-boost conditions) and makes the ECM fuel harder. Another positive is that it can be used in other vehicles with the right harness.

 

MP-8 ALL THE WAY...

Almost like it was built/designed for the TST... hmmmmm

 

I would vote MP-8. I have not tried the MP-8, but I probably will in the future. I have an EZ and it works fine. But I wish I had more granular control like the MP-8 and also would like be able to turn the EZ off with a switch, which you can not do.

 

I've run both the MP8 (marketed up here as an NADP Heavy Hauler), and the EDGE EZ stacked on the TST; and the MP8 fuels HARD, you definitely need big air to go with it. With a stock turbo, TST on 4/4 and MP8 turned all the way up, smoke was insane, I could block out 3 lanes of highway on demand. Once my new turbo arrives and my TST comes back with the twins program, I'm puttung the MP8 back on. Right now I have only the EZ on (BORING). Hope that helps.

 

I've had them all on the truck and nothing compare to the TS,Just hope you have a really good clutch!!!!!
