2.8 with 42's will run too lean and could possibly burn a cylinder or 4. you should get a wideband a/f gauge if you're going to mess with this stuff on your own. you should run around 11:1 WOT 11.5 at the leanest to be safe. interchangeable hubs do not require a puller.

The OP should maybe try the stage 2 tune(or custom?) with some 60's and a 2.7? I hear a 2.7 can be worth while with stage 2 and 60's......didn't stage 2 come with 60's? Or do u just not know my LSJ's lol?

For the cheapseats....
You can run a 2.8 on 42's (which are the STGII injector size). GET TUNED! You just have to adjust the PE tables in the tune to not dump into low 10s AFR at WOT. Elevation runs a factor into this, but I ran this setup in TN and in NM and that covers a good distance of driving in between.
The major problem you will run into with anything under the 3.06" pulley (STGII) to a 2.8 is that your intake temperatures will be too hot for a completely OEM setup and it will affect timing. Also the grade of gas you use will stack on the timing problems. For 2.8 and down, 60's, dual pass and secondary HE is really recommended. Meth is either or.

im just gonna go with a 2.9 and complete the exhaust, and get a cobra or e-p heat exchanger to finish cooling. Im not gonna try running a 2.8 on 42's because we have piss 91 octane out here. Ill finish it off with a trifecta tune, unless anyone knows of any REPUTABLE tuners in AZ.

some guys in texas had some misfire codes after he tuned them, and he blew up some guys engine. also theres a guy out here on 2.9 full exhaust and intake tuned by him and my buddy with a stage 1 balt says i pull on him harder than the stevo tuned guy.

well that could very well be bad tunes... but blowing up the motor can happen at the best of time, and is not always tune error... but with that being said if he has a bad rep, you are always safe going with trifecta, vince knows what he is doing, i cant say I have heard anything bad about him
