[RCC]

I have a 2004. 5 with the 600 motor, I have installed a edge ez and a afe air intake . I am considering buying a tst box because higher horsepower ratings and the monitor . Has anyone used this product,any input would be appreciated. Thanks, RC

Some believe the TST is a bit harsh on the drivetrain, and it is, but it does lay down some large gains, But also the Bullydog downloader is also becoming a contender

check this thread, he layed down 170HP on level 7 or so

The TST works awesome on a 600, if you are in search of more power you can run the EZ and the TST together for even more power. Just be careful of EGT's and boost pressures.

Buy the TST box.

You won't regret it.

I just laid down 425hp and 945ft lbs on TST's dyno.

TST and EZ stacked.

Don't forget a clutch or transmission upgrade.

I'm mighty fond of my TST, no codes or any problems since the reflash, but you gotta have some self control or the turbo and transmission won't make it.

tst is awesome i have it on my 600 and it feels like two engines now. i raced a subaru wrx starting at about 50 mph with the chip on 7 and he couldn't pull from me at all. althought my truck only has 5,000 miles on it and the clutch is gunk so stay off of stage nine

The new TST program is not as harsh on parts like old program.

New one comes on smoother

Yes, it can help with mileage.

If you keep your foot off the go pedal.
