Jet vs. Flashpaq

[phillips2024]

a lot of you guys are running the flashpaq tuners so i dont hear a lot about the JET performance chips. i am looking into getting a chip for my 300c but i am not sure on what road to take.

i am looking at the flashpaqs and the JET chips. im not sure what would be the better way to go.

and if i go with a JET chip, what stage would i go with? 1 or 2? from what i get the stage 1 is for stock engines and stage 2 is for modified engines. i have just an Intake on my 300c. could i go with a stage 2? and add on exhaust and all that good stuff later on? i do not want to spend money on stage 1 is later down the road i will need a stage 2?

any help will be great. my stock 300c isnt cuttin it right now on the streets haha

I do not have first hand knowledge of the JET chip, but it is a "piggyback" chip that is permanently installed on the car, plugs into the wiring harness to modify the signal to or from the car's onboard computer(s). I do not know if it modifies air/fuel mixture or if it just provides more aggressive timing advance for better performance (others may know for sure) but it is not updatable and if you want to get rid of it (i.e. taking your car in for a warranty repair) you have to physically remove it. Also the JET chip does nothing to enhance the transmission's performance, just the engine.

I have the flashpaq; the main reason I bought it was because it improves the transmission's performance DRAMATICALLY. They claim it ads 12 hp or something; I don't know. What I can tell you for sure is that it did ad 'responsiveness' when you hit the throttle; it feels quicker now for sure but I have not had it to a track before or after. But the tranny works Sweet now; like it should have in the first place. In autostick it shifts when you tell it to, rather than several seconds later. Nice firm crisp shifts too. In automatic mode it's still nice and smooth but not "mushy" like before. Plus I now have the "5th" gear option in autostick like the SRT8's do.

Other added benefits to the flashpaq are: (1) It can be updated on the internet when Superchips comes out with new features. (2) you can remove the 128 mph speed limiter. (3) you can adjust for aftermarket tires so your speedometer is still accurate. (4) it works as a 'scan tool' to access trouble codes on any OBDII Chrysler/Dodge/Jeep vehicle. (5) you can choose between different transmission options, raise the WOT shift points, and adjust between 87 octane and 91 octane performance tunes. (6) You can quickly re-load the car's stock program in about 5 minutes if you ever need to (although I've read it's best to wait 12 hours before taking it to the dealer).

I'm extremely happy with the flashpaq; like I said my main objective was to make the transmission work like I felt it should have from the factory, rather than the slushy "grandma car" shifts that it had stock; and it more than met my expectations.

thank you very much for the post, seems like an open and shut case here ahha. i will look into the flashpaq bc i def want to get rid of that autostick lag.

For the not-uncommon price of $150 for a used Stage II Jet Chip, phillips2024, there is no better value in terms of a performance mod for your 5.7L Hemi. To the surprise of the many uninformed who opine on the Jet Chip, it not only gives your engine an immediate power boost by means of much more agressive fuel and timing management, but it gives your tranny a much needed boost as well by raising tranny pressure noticeably. Shift lag becomes a forgotten nuisance. See my post here: Modding the LX Hemi

to examine the benefits provided by each of the various mods I've added in my quest for perfection of the 5.7 Hemi.

As you'd be doing, I ran my Jet Chip with intake mods only for several months, then added a free-flow exhaust system. I went with the Magnaflows, which work superbly, but I'd recommend the newly released Corsa system for it's lack of resonance, especially with MDS engaged.

If I didn't need the Superchips tuner to raise the speed limiter I'd have never purchased it. The the majority of tests show that the Jet Chip produces more power than does the Superchips tuner, and it has a better fuel map. I had to add the Jet Chip back on top of the Superchips tuner to cure a lean surge at high speed, something that had never occurred when using the Jet Chip, under any circumstances.

Even at supporting vendor pricing you can't go wrong with the Stage II Jet Chip, IMO.

Sorry...my fingers aren't working this afternoon! I installed the stage II a couple weeks ago along with going back to stock tires for a trip to the drag strip and go nearly .3 better in the quarter mile. I don't know which had more effect but after installing the Jet II my butt dyno said it did a lot. It is advertised for all the mods that I have done to date. I give it a thumbs up.

Your experience with the Jet Chip mirrors my own, Midnightsun.

Continue to enjoy it. Also consider the Robert Shaw 383-170 176-degree, failsafe, thermostat and the GSM fan/torque/ESP mod. You can read more about the cooler tstats here: Alternate thermostats for the LX Hemis

A cooler tstat is only half a mod, needing a fan mod to keep your engine cool in town and in heavy road traffic.

Only the GSM mod will allow you to totally disable ESP interference with your power application.

I tried the flashpaq for almost 4 weeks and ended up returning it for a refund. Car pinged real bad with the 91 octane tune. The 87 octane tune was not an option for me, as I didn't want to dumb-down the car to save a few dollars in gas. Most everyone will disagree with me, but I also didn't find the torque management and/or shifting in automatic a real improvement over stock. If you like raising the RPM shift points and/or using the slap-stick, the flashpaq does a good job.
