There was a thread a couple days ago where a guy with an '02 HO like yours made 291/746 with a smarty and stock fueling I highly recommend the smarty programmer and it looks like the HO's respond well to them. Smarty wouldn't stack with another programmer, but it'd make a great replacement.

To answer your question though you could add a fueling box and keep the sc programmer. Blue Chip and TST both sell fueing boxes and these would take care of the boost fooling.

 

But in another thread he was talking about 100 hp injectors. Smarty and injectors is tough to touch- even with the mighty tst. I'd think his ETH would make more power with the injectors but would offer more adjustability with the tst =P

 

the blue chip/superchips stack isn't a good combo, I removed my van aaken & tried a superchip tuner once & it gave me less power than just the blue chip alone & sent my egt's through the roof, i'd say you may as well go with a smarty seems like everyone eventually does!! LOL anyone tried a smarty/bluechip stack yet????? thanks, Dusty

 

i no we talked about this about 2 weeks ago but for my truck, not sure if i just got one of THOSE trucks that responds very very well to upgrades but with my truck, a TSTcomp/Smarty/DRAG comp(in EZ mode) was amazing!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !
