living in Cali has it's benefits, but modding isn't an easy one...

who's here from the SMOG-checking-state?

what mods? do you pass?

 

Magnuson Radix supercharger, end of worries

 

CARB sucks. Just register the vehicle in another state

 

there's plenty you can do and be CARB legal.

 

LOL - anything a little cheaper to start with?

 

Tell us a little bit about the truck, and what your goals and plans are first..

 

it's an '01 Denali XL - people hauler (not really offroader)

just want more pep, better mileage, and not obnoxious (but throaty sounding is totally cool) when you get on the gas

 

custom tune and LT's with some hi flow cats (if they are good enough to pass smog that is)

 

yah, that's the bugger - SMOG...

LT's?

 

I was able to get mine smogged with 553rwhp/585rwtq...complete with visual.

What the smog tester could see (all CARB approved): Maggie 122hh (okay, this one was a little iffy but he could not tell the difference from a 112), AFR 225 heads, Volant CAI, JBA short headers, Magnaflow catted y-pipe, and Corsa Touring catback.

What they couldn't see/didn't notice (and is not CARB approved): LS6 block, Eagle 4" crank, Diamond -7cc pistons, Crower Sportsman rods, and LPE GT2-3 cam.

Obviously, the tuning has EVERYTHING to do with passing the emissions test...after that, its up to the tester as to whether they will nit-pick your mods.
