I've noticed quite a few people have these and I looked it up on Turbo Tech Racing and I was wondering what kind of HP gain if any is there?

 

0 hp gain, it tweaks ur tranny

 

So... for what? I really don't quite understand what it does.

 

tuning > B&M

 

isn't it just a plug and play for the tranny?

 

It makes automatics shift harder/faster. You can feel it when you go from 1st in to 2nd really well.

A tune is allot better but if you can't afford to get it tuned/ can't find someone. Its a cheap alt

No, you have to splice 2 wires.

 

Screw messing with my wires, I'll just find me a tune!

 

I have one installed in my 2.4, I like it a lot. I decided to get it cause I don't plan on spending money on a tune untill I actually need it, all I have right now is the shiftplus and an injen CAI. I didn't splice the wires because I know I'd eventually take it off so I just cut back some of the rubber covering around the wires and set it up that way (I didn't want to cut wires). And think of it this way, a tune is definatly better but seeing your mods I'd wait untill you at least have a full exhaust or something.

tune>shiftplus
$250 for tune<$40 for a shiftplus

 

The Cobalt's autotranny has an electronic pressure control valve -- the B+M shift-plus increases the tranny's internal fluid pressure by altering the signal to the electronic pressure control valve to make it shift harder.

 

It's well worth it. You're only taping into 2 wires, it's not gonna destroy your car. If you wanna go back to stock just take it off and tape over where the connections were made with electrical tape.

 

such an easy install and well worth it IMHO.... I was amazed at how much firmer the car shifts.... I haven't tested, but it definately cuts some time off your 0-60

 

what happens if you have that on and get a tune?

 

If you get a tune then you no longer need it. Just take it off and enjoy your new tune.
