Thanks Mike! the new gauge works flawlessly! I will send mine back ASAP
Glad we could help! I'll be curious to see why yours ended up so loose.
mine was a black face with orange neddle dont know the serries i bought it from shield at the farm show and took out my autometer and installed the isspro and it rattled all the way home and did til i sold it what about this new promaxx series does it do data loggin currios to know for sled pullin
Sorry, I missed this post before! We have a smaller orfice available for the gauges which cures most issues.
The Performax series has peak value recall as a standard feature, and you can optionally get a PC-based datalogging system. I pasted a write-up below.
Thanks,

EV² vs. Performax™
The Performax and EV² series share many attributes: Stepper motor movements, LED backlighting, and solid-state sensors. The EV² individual gauges cost more than the Performax counterparts, since the gauge must contain the processing power, while the Performax processing power is mostly in the ESP controller. The Performax series uses an underhood controller (the ESP) which connects to all the sensors (so you don't have to run all those sensor wires through your firewall). There are 3 common wires which run to all of your gauges (up to 17 total), simplifying your wiring and allowing you to move gauges around to any location. The Performax system also includes the Total Recall™ feature, which provides the ability to view the extreme values of all functions connected to the Performax system. For most functions, the stored value is the maximum value, but on fuel system pressures (Fuel, HPOP, and Rail Pressure), the lowest value while under load is recorded (requires the use of Performax boost gauge sensor). This allows you to focus on driving down the dragstrip or pulling track, keeping it in the groove instead of trying to see if your fuel pressure is dipping at the end.
The ISSPRO Performax PC Datalogger is an optional interface module and software package which allows your Windows-based PC to record all of the data being read from the sensors connected to the Performax ESP controller.
The module connects to the gauge wiring in place of one gauge (or you can wire in an additional gauge connector in a convenient spot for the module), then connects via the included cord to the USB port of your PC.
The software displays actual values for all sensors connected to the ESP while it is logging (there is a start/stop button on the screen). When logging, the software writes to a comma-separated-value (CSV) file to be opened up in Microsoft Excel (or a similar program). The data is logged for each channel at 5 samples per second. You can use your spreadsheet (e.g., MS Excel) features to analyze and graph the results.
The data is logged for all sensors connected to the Performax ESP, regardless of whether a corresponding gauge is installed. You can have all 17 channels connected to sensors for datalogging, even if you only have room for 3 gauges in your truck.
If you are not interested in the Total Recall or PC Datalogger features, then EV² is the likely choice when installing 3 or fewer gauges. For more gauges, the Performax system is more cost effective, especially when installation time is taken into account.
Pyrometer temperature compensation
One significant benefit of ISSPRO Performax™ and EV² gauge systems is the temperature compensated pyrometer, unique in automotive pyrometers.
Conventional pyrometers just measure the difference in temperature between the probe tip and the leadwire end (typically at the gauge head). The industry standard is to calibrate on the assumption that the gauge head is at 70° F. In an enclosed cab on a hot day with a dark colored interior, a gauge can reach well over 170° F and will be very slow to cool off (the pods act as a good insulator). This will result in your pyro displaying a temperature over 100° F cooler than the actual temperature, in conditions where you are likely to see high temperatures. Because of this inherent inaccuracy, ISSPRO Performax and EV² pyrometers utilize temperature compensation circuits and show the actual probe tip temperature.
