Mo Go - but a little more fuel cost

Reviewed By Thomas M (Carbondale, CO) Reviewed for a 2001 GMC C/K 3500 —7/2/2010 8:18 AM

Slam dunk to install. Had to remove 2 fuses but down loaded with no problems. Tuned to "regular" gas in an 8.1 GMC and had some ping but called in and the regular setting is set for 87 octane and I had 85 so bought some octane booster and solved that problem. Later fueled with 1/2 premium and 1/2 85 and so far no problems. Power gain is noticable, especially in mid range. A little dissapointed in the 87 octane setting as I was after performance gain as well as cost and ended up costing about a dime more per gallon for the 87. Haven't run enought to notice any fuel milage gain at this point and it is hard to keep your foot away from the firewall so we'll see if the additional performance is worth a dime/gallon. At this point I would recommend the programmer, however.

EGT and MORE

Reviewed By mark W (Everett, WA) Reviewed for a 2015 Chevy Silverado —7/29/2015 2:54 AM

I bought the EDGE INSIGHT so I could read what my truck already knows. Install was a snap into my 2015 Silverado 3500 duramax and now I can view my EGT without drilling so I know when it's safe to shut down when I'm towing. Pre turbo EGT isn't available but I'm able to use my non-towing EGTs as target temps.

Jet Performance Module Reviews


Noticeable economy improvement

Reviewed By Travis D (Nashville, TN) Reviewed for a 2008 Chrysler PT Cruiser —7/12/2015 7:40 AM

I installed the stage 2 performance module after installing: Airaid intake Jet throttle body spacer Mishimoto 158 degree thermostat Msd ignition w/ vms 10mm wires JBA cat4ward headers & dei titanium wraps The module has really made everything play nice together, and I'm seeing about 30% increase in fuel economy! Well done, Jet! The only reason I gave 4 stars on installation is that you have to remove the air intake and power steering fluid reservoir to get the module to fit.
