    Default Programmer & Upgrades

    So i have a 2002 Silverado 1500, with a 4.3L V6 Engine, i was wondering what would be a good programmer for my truck? Also what would be some good performance upgrades that dont cost to much?

    I've been very happy with my Hypertech Max Energy programmer, but I do have a different engine than you. As far as I'm concerned, the most cost efficient performance upgrade is an intake, the second being exhaust. Helping the engine breathe makes a big difference.

    Intake, headers and exhaust are where I always start. A programmer would be a great addition as well. Beyond that, it depends on what your budget is.

    I would consider this: Forget about the programmer...talk to Justin over at Blackbear Performance, and he'll get you setup with a new custom computer module. In my case that was much, much better than the off-the-shelf stuff. Google it - he's got a web page. Its a little more expense but worth it.

    New air intake and exhaust will help also. The other upgrades are just like pounding sand down a rat hole, IMO.

    These three upgrades seem to get you the most bang for your buck...

    Exhaust and CAI are both good performance upgrades. Also if you are not using synthetic motor oil I would switch your fluids over. Synthetics will improve you millage,keep your engine cleaner, better cold starting, and most of all save you money.

    Let me know if I can help out.

    More on Blackbear

    I just did the standard version for around $260 if you keep the core. MPG is around 1~2mpg better (that wasn't what I asked for...you tell him what you want specifically), but the power increase is very, very, very good. He also fixes up the shift points for you. Its amazing how constipated the factory settings are. Compared to the off-the-shelf stuff this was much, much better for me, and I tried both routes.

    The data cable version would be even more precise for your vehicle, I would go that way if possible.

    Everybody who drives the rig now makes comments, even if they don't know about the upgrade. "What did you do to this...This is cool!" is generally what they say...

    Thumbs up progrmmer and upgrades

    Ive said this on other replys on this site, but I like the Diablo programmer. After you install what tune you what (87 91 93octane) you can adjust these for you truck, add timing, injector slope, shift points and much, much more. Just take your time,read the instructions and go to there website for more tuning info. The nice thing about programmers is you can change your tune and not have to send your trucks computer back to tuners or pay deposite on another truck computer. There are alot of people out there that are good tuners, and some that are not. If you really want to get your truck tuned dialed in, try looking for a Diablo tuning dealer near you.

    I have the Max Energy for my 4.3. It definitely helped but a custom tune would be much better. I got a deal on mine is why I got it. I looked last year for the Diablo programmer but it's not for the 4.3. A bored throttle body from cfmtech is a great addition...love mine. Throttle response was improved, especially.
