I'm quite sure someone has already asked this question, but I'm new here haven't found it yet.

Can you do the install of the stage 2 kit yourself, or is it going to require a GM dealer to reflash the ECM?

 

Dealer has to reflash.

 

fair warn you the stock pulley is a real b**** to get off I still havent gotten it off just ordered the zzp puller well rented it to give it a shot if the doesnt work will have to take it to the shop to see if they cant pull it with a press, already tried regular puller, impact gun, and propane heat to try and warm it up a little no success. But yes it will require a gm dealer to reflash the ecu

 

can you self install the stage 2 kit then take it to get a reflash ? or is it not safe to drive it with the stage 2 kit installed while going to get a reflash.. Just curious

 

from what I read it is only 2 hours shop time to have stage II installed...and no warrranty issue after...seems like a no brainer....

 

It shouldn't hurt your car if you don't do it too long it just means your car is going to be running very rich. My advise would be to install early and get it to the dealer that same day.

 

Everybody says GM will warranty it but my thinking is some dealerships might pull the good old you wouldn't buy stage 2 if you wern't going to abuse your car IE: race

 

You cant deny someone warrantee because you "figure" they are gonna race because they bought parts from GM, that were tested by GM, and installed by GM.

they could try. but good luck explaining that one to a judge.

 

How many people will actually take it to court? You gotta think of all the warranties voided by mopar and the fact that no action has been taken

edit: don't think for a minute certain dealerships won't bring your car in hold it for a few days and then refuse warranty because they found signs of abuse.

 

Thanks for answering my questions guys.

btw, if a dealership tries to pull that sort of thing with your warranty (especially if it's the dealer you bought it from) call as many of the sales folks as you can and complain using the phrase "genuine GM" and "if you want my future business". Raise enough of a fuss, and I bet you they'll honor your warranty. If they don't, file complaints with the BBB and see if you can complain to Chevy about that dealer. These guys aren't stupid enough to lose someone who's bought a high end model (even if it's not a Tahoe) car from them (especially if they're the type to go and complain about it to whoever will listen) over repairs that are in the $500 range.

 

I just got my stage 2 in from my Dad's dealership in MI and he told me that part number brings up 1.5 hrs of labor, which most dealerships SHOULD charge (but don't have to). Some dealerships won't do it for that because they haven't done it before and don't think they can get it done in that amount of time and don't want to lose a bunch of $$$. I've called 5 different chevy dealerships in the OKC area today and the lowest anyone will do it for is 4.9 hrs. One shop even told me $700-900 for the f***ing install. Bottom line is, GM recommends 1.5 hrs, some dealerships will do it for that and the ones that want to rip you off won't. I talked to the mechanic that installed one in MI and he told me to just do it myself, it's rather simple and bring it to the dealership and have them reprogram it (1.0 hr of labor). Don't worry, he said it will run bad, but a few miles will be fine to just get there and get it programmed.

 

I can do the whole kit and put the stage 2 tune on in about 80 minutes, included a drink break, but then again I don't think GM likes HP tuners used to get this stuff on thier cars.

 

are there any good pointers you can offer on getting the stock pulley off the supercharger???

 

Use a 20 tonne press. Thats what I used.

EDIT: Try the pulley puller first but it might be on too tight.

Your dealership will cover the kit under warantee if you install it yourself but they wont cover you for the work you put into it. I got my local tech to do it in 2.5 hours, I figured it was worth it since I was pretty much the first with the kit installed, I didnt want to deal with any problems down the road. Once your done, drive down to the dealer smoothly and get the reflash (might charge you for labour thought)

 

how would you get a 20 ton press in there? i mean seriously, are you saying that you pulled the whole supercharger??

 

Uhhh take the s/c out...

Did you read the manual?

 

Aye, you need to remove the SC to get the STOCK pulley off. Once you did that you can swap rings of the Stg2 hub without removing the SC.

 

what manual??? lol i havent gotten it yet, on the way...i am trying to get an idea before i get into it...want to be efficient if at all possible...

 

ok, so i have most of the stage two done, well maybe most of it. injectors are in and old pulley is off and supercharger is on the bench with the hub half way on and i cant get it any further, my current method jus wont do it. any suggestions on how to get the new hub on there...like what you used. one person said they used a power steering puller and it worked great for me as well...any hints on how to get that B**** back on there??? thanks a lot very useful posts so far...very pleased with all help received...

 

If you can get the hub back off then take it and put in in an oven or hot plate for about 30 minutes then quickly put it on the shaft and you should be able to drive it on using a hammer and block of wood. Another method I used was to take a stud that will screw into the snout, heat the pully, have a nut and washers ready, put hub on with washers and nut then wrech the nut in pushing pully on.

 

ok thanks, i am leary about jus beating it on because of puttin pressure on the shaft...i will try the heating method...thanks

 

i wouldnt do the beating method due to the bearing you dont want to take the chance of messing it up

 

yeah, so i got it heated and was runnin it on there with the bolt and washer method...i got it all but about 1-2mm from flush and am bustin bolts...i cant figure out how to get it the rest of the way on...any suggestions???i mean its so freakin close i cant stand it...

 

ok i jus measured it and its 1mm or .036" ....so i dunno if thats close enough or what ... kinda stuck...

 

f it im about to go to the dealer b like listen if i get the stage 2 kit and install it and i let u do the reflash would it b warrentied? im so about to do it i dont wanna b charged for 5 hours or labor on a stage 2 kit as they told me itll take unless somone can find on a gm site taht it says itll take less time to install and i can show them taht paper in writing to prove them wrong
