You will need to uninstall the B &M Shiftplus fist. Trifecta will tune the transmission for you.

You will only gain 5-10 Hp with a tune, but if you don't plan on doing any more performance mods to the car then the tune is the way to go.

If you think you will add more parts like header, downpipe, pulleys, cams or anything else then you need to wait to tune till after you install everything.

ya i have a 2.2l ls with intake, catback 2.5 2.4 intake many, thats just hte bolt on's. i got the tune for my 07 about 4 months ago and im rely glad i did get it. you wont see a huge diff but my gas mileg went from 35 mpg to 40 so im inpressed. but i would say to get the 2.4 cause he said thats mostly the onlything he can tune is that so get that then the tune.

okay so my shift plus has to go? are you guys sure about that i have herd of people leaving them on....and where can i find a intake manni, i thought about doing that any way good point of getting it before the tune *DOH* it hink if i get the tune with it then tune will compensate for it being on am i wrong here?

Did you say HPT supports the 07 2.2?

Proof?

lil_kano

any "performance"/"bolt-on" modification you make to your car is not tuned for in the car stock ecu. each mod makes a difference in performance and need to be tuned for. so what every one is saying is that instead of getting the tune first and doing more bolt-ons later, get the bolt-ons now and THEN get tuned. this will allow your tune to be more precise with your mods.

maven im prolly the wrong person to ask but i read some wher e hpt now supports the 07 2.2 and i unferstabd about the bolt ons then i tune....but can i tune with the shift plus on? and where can i get a 2.4 mani.

if you get the computer tuned dont get the transmission tuned from trifecta you can leave the b&m shift plus on. but they can tune your transmission as well leaving no need for the shift plus.

and honestly just get the transmission tuned as well and ditch the b&m

What?

LOL i think he meant to say if u dont get it tuned u can leave shift plus, but if u get it tuned ur gunna want to take it off

Shift plus sucks compared to a tranny tune. The transmission tune comes with his package, so you might as well get it.

I've heard you can leave shift plus on, it does nothing to affect the timing of the shifts.

CED has the kit

boltedbalt

so keep shift plus after tune or no? and tune with it on right?

and will spark plugs affect the tune? i dont think it should mabey by a tiny bit right? im need some new plugs im thinking e3

erm bump!

ionit3

io wouldnt keep it, and depending on what u do, vince would have answers for u, but one step colder or two step wont hurt depending on what u do

Sentry

No, after a tune there's no reason to have it on.

EvilleCobalt

I'm really not trying to sound like an ass here but I think you need to do a little more research before you start modding more. Your questions have already been answered in previous post. And as for the plugs don't go e3. You will be perfectly fine with the stock plugs unless you add NO2 or forced induction. My old 2.2 had full bolt ons with a tune on stock plugs with zero problems. Just trying to help you out. Research untill you're blue in the face because most of these topics have been discussed 100x over. Good Luck!

Well one step colder after he does a lot more won't really hurt but the stock plugs are actually quite good. 2 step colder definatly don't do unless you're boosted.

ionit3

yea i thought i mentioned that. woops

HPTuners does NOT support any model year L61 engine in the Cobalt. They never have.
