Is a plug in module worth the money?

[Marty85]

Ive been wondering whether or not a jet chip or something similar would be worth the money. I have done a search on this and have seen many people say they felt a difference and some say that the tuning in these modules is no different from the stock tuning. I can get one relatively cheap here...

Also I cant just take my computer out of my car and wait for a week while it get it sent off to get it reprogrammed nor do I have the money to do this (350 dollars is a little steep in my opinion and could more than deal with factory for that much).

Thanx in advance for any opinions/facts anyone can give.

currently no HPTuners support for a 3.4... i don't guess they plan to, either.

if you want to buy it, buy it... i can think of a much better use of $350 though.

Well its not $350. Performancecenter.com has it for only 232 bux for a stage 1 to go in an automatic but I was just wondering if they were any good or not.

any recommendations on JET SCU 2000 Speed Control Unit. allows adjustments in the transmission shift points and speedometer calibration for vehicles where tire size or gear changes are required. It also eliminates the top speed limiter http://performancecenter.com/products/?productID=662869 worth a HUNDRED Dollas??
