any of you guys have experience with the Superchips FlashPaq Tuner? for the 4.7l engine supposedly it delivers 21.9 hp and about 19.4 ft lbs torque more.

how do these chips work? i know you plug it in through the obd 2 port but do they increase engine wear/ strain etc?

 

Yes they are a plug in.


Do they work, well yes they do but the numbers you CAN gain might be different then what they mention. You will need Part Number: 3865


Anything that you do can adverse the engine and other parts but it is a good investment. SCT Tuners make a good one as well as well as Hypertech.
