ok so i live in Colorado right now at like 9,000FT and run 42's and a 2.8 with an HP Tune on my car and i was told that when i move to Washington im going to need to upgrade to 60's due to being at sea level and having a 2.8...is this true or will i be ok with my 42's? i have some mods also

1.75" Header - 3" DP w/High Flow Cat
Intake
Front Mount Heat Exchanger
Colder Plugs
Magnaflow Muffler

Any info will be greatly appreciated! thanks

 

either 60lb injectors or drop to a 2.9. if your still on stage 2 tune, drop to a 2.9 before you leave colorado. would suck to be passing someone on your trip and blow a piston.

 

ya, i have a custom HP Tune on my car now with a 2.8 pulley, thats my concern i dont wanna hurt my car or starve it of fuel
