i was looking online for a performance chip to put on my GS4 in the future, and i came across the JET performance chip. they sell it for $299, so it seems legit. i just need feedback on if its worth buying?? so let me know.

 

Whats the gains with that chip?

 

search on here for JET CHIP they worthless and a gimmick

there is NO real chip for our cars

 

Idk, I've Looked but I couldn't find anything

 

Ok, well I'm not getting that then. So what other performance upgrades can I get for my GS4?? Cuz right now I got an intake and bout to install an exhaust on my car.

 

I've been modifying domestics my entire life, and I'm guaranteeing if will probably do the same thing they do on the cars I love. They will probably change the temperature that your electric fans turn on, and slightly modify the spark table. They might also "fool" the ecu into thinking the engine is running cooler to put in more fuel and use the new spark table. But you probably wont even notice this. I'd steer clear of any "chips".... Just a giant waste of money. I would only buy chips, or a tuner on a diesel truck.

 

bigwes if u type Jet performance chip in Search on the top of the page u find lots of treads that been discuss a long time ago already most people saying its useless get an SRT intake or APEXI NEO
