Hello Everybody!
I Got A 2.80 Pulley And 44lbs Injectors To Install (alredy Did Sparks Plugs) So Here My Question Can A Chevy Dealer Install Those And Do The The Stage1 Reflash ? It Run Ok? I Got A Dealer It Will Install Stage 2 For $300 But The Dont KNOW Yet Is A Aftermarke Parts

 

gm won't put on the 2.8
well they might, but the car also might get flagged.
that is bad.

44's?

 

I AM SORRY WHAT U MEAN WITH FLAGGED AND YES 44 LBS I BOUGHT IN COBALTPERFORMANCEPART THEY ARE A DIRECT FIT ALSO ....

 

holy caps batman!

flagged, as in warranty.

stock stage 2 is 42.5 lb/hr injectors. so the flash will be for 42.5's not 44's.

 

WELL WARRANTY DONT GET VOID UNTIL THE CAR PRESENT A PROBLEM CAUSE FROM A MOD THAT U DID A CAR! THANK YOU I KNOW ABOUTH THE REFLASH NOW!!

 

2.8 is borderline to small for that size injectors. lots of people do it but i didnt want to risk it myself.

 

depends on what supporting mods you do.

you "can" get away with a 2.8 on 42's if you know what you're doing. of course, one has to know what to do to get away with it, and safely at that.

 

SO I 44 LBS INJ ARE ACTUALLY BETTER WITH 2.80?? ANYWAY THE GUYS FROM INTENSE RACING DID A 2.80 WITH THE 42 LBS LUCAS LOOK IN 3800PRO.C.......

 

The GM stage flash is not going to work correctly with 44 lb injectors. You will need to have the car tuned by a shop or someone with HPtuners. You might be able to get away with a 2.8 with 44 lb injectors but it might be borderline. I would also get some cooling mods as well if you actually want it to be "safe". If you have the install done by GM it is a good possibility that they will note it in your car and next time you go in for warranty work they will give you trouble even if it is unrelated.

 

finnally something clear!!!!!!!!!! thanks...

 

i havent heard of anyone using 44lb/hr injectors in their cobalt before.. u might want to re-check that..

 

cobaltperformanceparts.com

they are on there.

 

I would think they would work ok with the 2.8. I know a couple guys up here running 2.8 pulleys on gm stage II injectors and tune without a problem. You can't get a stage reflash at any dealership without the auth code that comes with the kits.So I think your only option is someone with hp tuners.

 

well i hear all the dealer use a tek2 program from gm..

 

I would get a Custom Tune when you do your install. I had the GM Stage 2 tune with my 2.8" for a day and my car hated me. It was pulling timing and bogging a lot. I would not recommend that tune with the 44#'ers and the 2.8" pulley.

 

well yes is a 42lb injectors cpp say is 44 but that not right you look in pte website (manufacture) is listed as 42 lbs. so i can do a stage1 reflash and 2.80 pulley and belt! stage one is 42 lbs anyway.....

 

yeah, if you had the stage 1 reflash, it would work.. but i think you might have a hard time getting them to install and aftermarket setup.. personally, i do not think they would do it..

 

nope they say is kool but i know they will flaged my car.... but who buy a tunner car and dont mod? who bought a camaro and dint change anythig on it ?toll them that and they underthang
