Holy crap!!!!!!! I drove Blackjack's car today while he was out here checking out my lights and it is sick fast. :yahoo: It shifts like freaking crazy. The shifts are really firm and right where they need to be to get that beast moving like madness. He was telling me all about the custom tuning he's doing with his HP tuner. If he sees this I'll let him post all the specifics. It is crazy fast though. I don't think I have ever been in a faster V-6. It completely stomps the crap out of my first alero and I had some decent things done to that.

Long story short though, I'm getting that HP Tuner for my car. After driving his I know that it is worth every single penny. :thumb:

the turbo is installed?

Thanks for the write-up on that. Just to clear it up, I confused him a little with talking about the HP Tuner for his 4-banger. He meant the PowrTuner that I used on mine.

no, turbo not installed yet, just testing some theories with tuning so far. Believe it or not, there's still alot of untapped HP hiding in that PCM. It's nice to know that so much can be done with simple timing and fuel/air work.

I think I can reasonably asses that once the hair-dryer is installed its just going to get stupid at that point. That poor transmission :Noooo:

Some of the issues I worked out was adding some timing, clearing out the fuel trims and starting from scratch. Further, I took out the fuel related Torque Management settings that related to cutting injectors under torque-abuse settings, and left it to just reducing timing to manage torque control over the transmission. There's no longer a speed limiter, and the rev limiter has been moved up to 6200. Line pressures in the tranny have been increased, and shift points moved up to 6,000 under WOT.

Next phase, I'm dropping in the 42.5# injectors, the 80mm MAF/IAT, and the 75mm TB off the 4.3 Vortec.

Keep in mind, I haven't even installed any ported or polished goodies yet, so there's still more to come. I figured while I wait for my headers I might as well get deep into that PowrTuner and find out how far you can go without power adders.

how much did that all cost ya? ^^

be specific cuz i'm stoopid. I'll tell you right now, I probably paid alot less for all my parts than most people could get them for.

so, are you offering tuning to other members?

unfortunately I cannot. DHP went way out of their way to accomodate all my crazy ass requests, and I only purchased the basic PowrTuner package. If I were to tune other people's cars, then ethically I'd have to pay over $2,500 for their special open software for people with performance tuning businesses. I feel if I were to pull some B.S. like that, it would seriously compromise my relationship with them. Although, I really would like to help you.

Yo BlackJack, are you going to attempt to build one of the fastest All Motor Aleros. It sounds like it. I like your ideas and setup for the PCM, you seem to really know what your doing with that thing. Goodluck with it man, but don't break anything in the mean time. Upgrade everything you can, especially those injectiors, with those types of pushes. What do you currenyly have done to the car now? And ur running the 3400 SFI engine with the Stock Trans right?

no, not attempting to build the fastest all-motor. I'm preparing for a turbo build that is currently in progress. Improper tuning is something that causes failure via detonation and melted pistons, etc.

This is the purpose for indepth experimenting before adding the boost.

How much horsepower u think you can get out of it before adding the turbo?

no idea. I'm not dropping money on dyno until after I get the turbo installed. All I can tell you is that it's significantly faster with just tuning. I would love to take it to the track/dyno and give numbers to help everyone out, but the track is over an hour away, the dyno wouldn't do much good because of expense versus personal gain and I'd have to retune once there just because of ambient temperature and altitude differences.

lets just suffice to say it "feels" a hell of alot faster at this point.

ok, here's one for comparison. On a Private road (not public street) I ran against my buddy with his 00 Malibu, 3400 transplant, 62mm TB, FFP Underdrive pulley, S&S headers, CAI, full 3 inch Borla exhaust, and mild tuning (DHP's 1.5 file), and I was just about keeping up. Mine only had WAI and medium tune done by me. By 1/4 mile distance he had me by a car length. Not bad for as few mods as I have. Oh yeah, and I had LOTS of extra stuff in my car. So tuning does alot of good I'd say. Now imagine if I had his mods to top it off, plus PnP ULIM/Heads.

black, your car is a beast

i kinda wish i would have drove it LOL, but won't lol

did ya get the open source yet?

no open source, because "open source" only applies to cars that DHP have developed code for. This is why there is an OBDII port on other GM's but PT doesn't work for them.

I was the first '03 Alero that DHP developed for, so that's why it took a long time for me to get it.

tuning is very huge, there is a former gtp turned cobalt ss guy with minimal bolt ons running a 12.6 1/4

nice, that car is gonna be nuts :beerchug:
