Ooh yeah i know im not gonna get anything close to 230WHP, i figured the engine HP would be around that ... no?

I wouldnt expect a mail order tune to deliver 30 HP. I would expect it to feel like a big difference in speed, due to the trans shift points, and other settings adjusted for performance, along with the HP gains(15 HP?) I am just guessing though. Obviously it would depend on any supporting mods that you may have as well.

Yeah i was talking about the PCM in addition to the CAI i got and im about to order a HV3 intake insert. so i figured with those 3 i would hope it would be around 230hp, not whp.... and i would assume that i would notice a big difference compared to stock...

That sounds pretty close to me. You will notice a big difference with those items. You may have to modify exhaust to make it run the best though.

theres really no point in getting an intake or hv3 until you get your exhaust opened up. (u-bend delete) your givng your engine all this extra air, but it cant do anything with it, it has no way to get rid of it. then if you put a tuned pcm on top of that.... sounds like a recipe for disaster

personally I wouldnt worry about the CAI being on there by itself without any exhaust mods(as I did it with my SC motor and had no problems). but I would get the DP before doing the HV3/tuned PCM....you dont want it to be backed up and unable to get rid of the exhaust. I agree with Jakegday...
I used DHP PCM And it was great. No problems to date. I've seen many PCM upgrades on the internet and the only ones I would trust are Digital Horsepower or ZZ performance. Also I have a Dyno sheet With results from the DHP PCM. At the wheels I got 13.3 HP. My car has a 3800 series 2 naturally aspirated I have typical mods CAI,Exhaust,Throtle body,MSD Ignition upgrade, simple stuff. I was most impressed by the DHP PCM. I'm new to this forum and havent dabbled much with computers. Usually I'm spending most of my time under the hood. I'm not ASE certified but I've been working on cars for at least 15 years. Trust me go to the DHP Website. Even call there tech support ask any and all questions you have.
Is there a problem with ZZP PCM? I wasent aware of any problems. As far as a waste of money on DHP PCM .You dont what your talking about!!!! The PCM Has custom shift points, harder shifts it also monitors the engine and adjust timing and air fuel mix. All of this means better performance more horsepower!!!

I have no problems or complaints with the PCM itself. I still have not received my refund from 3800 performance and they have had the pcm returned at their doorstep for over two months. I have emailed several times and they have not even responded to my e-mails about this. I will be looking for their phone number to call them next week if anyone has it or a different e-mail addy other than sales @ 3800. So far product good, service, extremely bad. From all of my orders in the past there has been no problems, just a problem getting deposit money back.
Your factory computer is set to an air fuel mix of about 15.7/1 way lean. a more ideal fuel mix is around 12/1 for all out performance WOT.this of coarse depends on engine load and RPM. to obtain this performance fuel number you will need a performance PCM to do the job. Theres also the issue of timing. By advancing the timing (this also changes with RMP) you can maximize an engins horsepower. The new PCM takes care of that as well. Dollar per dollar with the exception of NO2 upgrading to an aftermarket PCM is the best mod to do even if you dont have any bolt-ons (CAI,Exhaust). As you upgrade your bolt-ons your upgraded PCM will adjust to the new found fresh air. It will give a little more fuel a little more timing and BOOM!!

OK. I guess I'll have to take you back to pre-scool!!! Do you even know what a car is or are you borowing your older sisters moped then drawing from that experience to educate ME?!? Ok.Ok I can hear you cussing already but before you shoot another ignorant post my way contact Todd Collins at DHP tech support. I really dont have time for little ity-bity preschoolers but I shure Todd Wont Mind giving you the basics. Now You STFU!!!!! I WIN!!

12:1 is not a good AFR for peak power. it may be a good range for not running lean (actually 11.5:1 or so is better for that), but its not good for PEAK power. the timing advance on most off the shelf PCMs is too much for the mods that people are running. stock timing (~16* WOT) would be best.
you do know what youre talking about, but youre saying that the DHP is the end all solution to it all. no off the shelf tune will work perfectly with anyones setup.

I totally agree with what you said. your right no off the shelf tune will be perfect for everyones tune.Speaking generally for the bolt on mods that most of us are doing these tunes will work just fine. If you have a more aggressive build/motor combo in mind you could always contact DHP or anyone the does PCMs (I dont know them all or if all are good. Some better than others I imagine). Also I simplly stated that DHP is the resource that I used with good results 13.3 HP to the wheels. By no means an end all solution but for me a good one. The original post was asking about PCMs and if anyone had used them. I simply gave my advice, I thought thats what we do here??? Get others opinions about parts or mods before shelling out hard earned cash. See what works and what doesent. Also Ive never seen an engine with an air fuel ratio as rich as 11.5/1 make more power than 12/1 Not from Honda's to 3800's, big blocks or small blocks no matter the RPM. But if You say so than Maybe Its true.

DHP has been tried and true for many years with NO ISSUES EVER. ZZP, Overkill, Intense-Racing, etc...have all had PCM issues...I had FIVE ZZP PCM's for my car...all of which were messed up and in programming mode. Hence why I never recommend them to anyone. It also ended up toasting my motor about a month after the 5th one since it was my DD.
