my bro has a 2003 5.3L 4l65e rclb z71. he is looking for some more power-

he is wanting 2 get-
diablosport tuner
AEM brute force

is there a better programmer or intake for his truck? he already has custom cat-back exhaust.

 

yes, hp tuners! its worth it in the long run . as for CAI go with one that is reasonable in price, they all are about the same. maybe get some intake pipng from TRT and fab one up yourself.

 

With as many posts as you have I would think you'ld have read some good advice for your brother by now.
If he doesnt want to get into tuning himself he can purchase an already tuned PCM and swap it right in!

 

i dont know much about the 5.3L's. sorry all i know is heads/cam tune and he would have all the power he wants but hes a cheap ***. he has the money and wants the power he just doesnt want 2 spend it. i told him 2 get a nelson tuned ecu if possible. we will see. im sure he doesnt want 2 do hptuning. hes retarded i think. he would always bust my ***** about nitrous and how bad it sucks and then he goes and puts it on his el camino. he doesnt know what he wants

 

What?!! i was just saying that eventually down the road hes gonna prob want it. I know all to well. 1st i bought a hypercrap tuner, then i got a turbo and bought Nelson Tuning, now to help Allen and my self i bought hp Tuners. See where im going? If he wants a handheld i would just reccomend getting HP, but if he doesnt want to tune it him self I definitley reccommend a NELSON TUNE! Jusy My 2 cents.

 

Sorry Tim! I wasn't reffering to you in my post Some people probably dont have the time, patience or brains to figure out HPT, myself included

 

cool man , i heard that, this software is very intimidating, theres lots to look at and learn. BTW 02VORTECH, My uncle has a diablo tuner for his vette and it is a great handheld and you can also monitor data on it too.
