so i am new to putting performace parts on my truck but i am looking at getting a little more mpg........ i want to put jba longtube headers... corsa sport side exhaust, edge programmer, kn cold air intake, air raid throttle body spacer a hotter coil new plugs and fresh delco plugs? do you guys have any input on this i am reading diffrent threads and im getting kinda confused..... ps corsa does sound bad a$$ any tips on better parts or diffrent brands?

 

STOCK COILS, STOCK WIRES (save your money)
NGK TR55 plugs (2.25 ea)
jba lts cost??? if over 500-550 go with pacesetter lts
DONT buy the TB spacer its a waste
dont waste your money on a handheld program. get a mail order tune at the least.
Wheatley, Nelson Performance, Black Bear, EPS


whats the motor, gears, size of truck (RCSB, ECSB, CCSB)

 

08 sierra 1500 ex cab reg box 5.3l non flex, 3.73 gr, jba headers 390 for stainless, i was now thinking black bear tuner.

 

Agree with above. Handhelds are a POS. Go buy a second ECM jic your still under warranty. Local yards here we found for $40ish.

What are you goals with your truck?

 

i want better mpg with out loosing performance so if i do want open it up i can, i dont want to change my gears at all

 

3.73's on 18's?

 

better gas mileage can be done with a tune an CAI. the rest is gonna cost you mpg bc we ALL know that once you get the mod bug your gonna wanna go faster then the gas mileage really falls

3:73s are a great gear no matter what you decide to do. if you want it faster, more hp/tq then cam it an put a converter. the thing with wanting gas mileage will be that you actually have to stay with a smaller cam or the in city mpg will become horrible

 

iv'e got 20's

 

whats the diffreence with short tube and long tube headers?

 

oops, i posted in your first thread instead of this one. but basically what niff said was right on. cai, lts, and catback all got me better gas mileage with a tune. however, thats only when ur right foot stays calm lol
