Should I Get This Superchips Tuner?

[KMGZ400]

i can get a never touched superchips for 99-06 gm trucks 5.3 for 120. some local kid has it for sale he has never even taken it out of the box and said he will sell it for 120. i know these things go for like 360 new so im thinking ill pick this up. with that being said, are superchips good? will it make a big performance gain? im just looking for some info about it.. my truck is a ECSB 5.3 3.73 K&N flowmaster only engine upgrades. thanks

I'm not familiar with SuperChips. If that is the price and then new price is $350 then that sounds like a good deal.

Superchips is a nice tuner... and as long as his truck was returned to stock, then it sounds like a good deal, otherwise, it's just a paper weight.

[BlackZ71Silverado]

If he said he never took it out of the box, he most likely didn't use it. Sounds like a good deal for that price, they are not cheap. I would find out for sure if he ever used it before I bought it and found out it was not usable.

Double check the unit to make sure it will operate for your vehicle. The kid may not realize that if it's still locked to his vehicle it's worthless to you. Or it could be perfectly new as he states.

he never even used it..not even opened. some it 16 year old who just got his licsence and his dad wont let him put it on his RCLB 1500 5.3..

 

 

so its a good tuner? will it make a noticeable increase in power? what i really want is crisper shift.. my shifts feel kinda sloppy and im hoping to clean it up. dont care about fuel econ.

It will be a nice improvement for your 4 speed. You can adjust line pressure and shift points. There will not be a huge difference in power. But it will be pretty noticable change in how your drivetrain delivers the power.

 

I have a Cortex for sale in the for sale section. But $120 is a great price. Almost too good to be true.

 

Be sure to post up what you think of it.

ok thanks a lot guys. 1 more question, will it remove the 96mph limiter?

[Stevens03]

Remove... No... Raise Yes but remember, you should never go above your tire ratings

[KMGZ400]

i know i know, so what will it raise it to?

 

 

and im almost 100% percent sure i cant use this on my other trucks?

[Stevens03]

120mph for sure

 

You can only tune one truck at one time.

ok thanks a lot.

ok now one more question, should i tune it for 93 or 87.... is it really gonna be that big of a diffrence if i run 93? will it be worth it? and if i initially set it up for 93 can i tune it back to 87?

[Stevens03]

Yes, tune for 93... and you can change it at any time. You'll see the biggest performance difference at the 93 tune. You can also get away running 89 octane while the 93 tune is installed. But you won't get as much power out of it.

[KMGZ400]

well when i tune it to 93 im gonna obviously have 87 in the tank..... so do i just use it untill its all gone? or should i go fill up with 93 first?
