*** Do not use for prolonged high speed runs! Speeds exceeding approx 105 mph can result in high exhaust gas temperatures and damage the Diesel Particulate Filter (DPF) !!! .
*** All even numbered software (2-4-6-8) without timing are to be used for stacking with other after market power adding devices that also add their own timing. NO additional timing has to be used with the odd numbered software (1-3-5-7-9). Severe engine damage will result !!!
The SMARTY S-67 is not guaranteed to be undetectable.
Here's some of the latest news on the S-67:
The VGT levels are as follows:
1) stock ( makes for a somewhat sluggish throttle )
2) The Default one, good compromise between responsiveness and MPG
3) For Mileage! Less responsive than 2 but better for mileage ( Should be used for towing heavy )
4) As responsive as possible without creating too much back pressure.
Mileage will suffer a little with this one!
