i have had been running stage 2 w/ the 2.8 for some time now but was wanting to upgrade injectors

can i just install the 60lbs injectors with the GM tune and it run properly, or do i need hptuners

also i have in the mail the GM dual pass and upgraded intake gaskets for a build i was planning- do you think i should go ahead and install all that soon or wait till the engine is out and being built

just need some opinions for my set up

 

u definetly need hptuners to run the 60's.

 

yeah you are going to need some type of tune

 

see my fear is that if i go ahead with the install of the DP mod im going to have to replace the upgraded intake gastket (once installed) when i do the pistons/rods/studs and the head/cometic/valvetrain stuff

HPtuners is in the future but wanted a time frame to plan my mods and be prepared

best to wait and do it all at once, you think?
or should i do dual pass immediatly to safely run my current setup?

 

u might be able to do it but you can NOT go WOT at all or else your engine will go boom

 

elaborate,

I run my car WOT now and its just fine
i personally dont feel my injectors will run static on the 42.5s

or are you refering to the 60s w/ GMtune

 

lol ^^ no. dont run 60's with a stage 2 setup. good god that is asking for trouble.

go ahead and install the dual pass. no reason not to. you will be safer, cooler, and possibly a "bit" faster

 

i was talking about the 60's with the gmtune. I was thinking if you go really easy on the car until you can get it tuned and you might be fine with the gm tune. But for safety reasons and too save money in the long run i would not run the 60's on the gm tune.

 

definantly

thanks for your input

any thoughts on the GM dual pass mods?

 

you should not run 60's on a gm tune period? that's... that's... lunacy :O

 

my input at least ^^

 

no problem

 

if you have stage 2 already look at this group buy if u want 60's
