I just purchased a diablo Tuner and tunes from Bamachips. I live in Denver. Do I need to contact Doug to let him know that I am at 5280ft elevation? Wont my car run too lean (or rich) I get it confused which one it is?

I ordered from Bama too. When I did, I mentioned it..but he didn't ask the altitude or even seem to care.
I've tried the 87 perf, 91 torque and 91 race (shifts at 5900) and a modified race tune that I had him set
the shift point to 6300-6400. All run perfect in any temperature. I've never thrown a code or heard any
pinging.

 

I also live in Denver. I tried and returned the Steeda CAI with tunes from Brenspeed and then the C&L street intake with tunes from Bama... both made me pay dearly for the increased thrust above 3500 RPM with big-time torque losses under 2500 RPM. Really made the car unpleasant as a daily driver. I mentioned to both Brenspeed and Bama that I lived at 6,000 feet.

Brenspeed wasn't able to remedy the problem, and I really didn't give Bama much of an opportunity to do so. Got tired of shipping intakes and programmers back and forth. Now I'm running the no-tune Airaid intake. Well made, looks great, sounds great, but there's no real performance gain as far as I can tell.

Just my $0.02... I'll be interested to hear your experience.

 

Thanks for the replies MFers. I will post results. I'm not going to install for a couple of weeks thou. Either of you going to SteamBoat this weekend for the Mustang show? I'm heading up on saturday.

That's gotta be a first.. someone disastisfied with a Bama and a Brenspeed tune? Maybe if you had done before and after 1/4 mile times you would have seen the performance boost you get.

I believe your ECU is supposed to correct for elevation. That's why you can drive your car from sea level up to the mountains at 8,000ft and not have any problems.

 

Mishri-
So at a higher elevation would the engine run more lean or rich (just for my own personal knowledge) ?

I too live in Denver and tried the Bama tune. It was awful. The poster above explained how there was no torque down low and he was absolutely correct. I tried all three as well and just felt that it wasn't very good.So I soild the whole package as well to somebody on these forums.

I think the altitude made a difference (for the worse).

 

As far as losing torque down low (under 2500). That may be the case, these motors (N/A)
or known for that. Peak torque doesn't kick in until much higher in the RPM's. I don't understand
how your DD is hampered by a even a little less torque loss under 2500. If your just puttin' around, do
you need the torque? Your still going to be quicker than 99% of anything sitting next to you.

Maybe the fact that I have an Auto, I don't notice it. Maybe from 0-20 mph it may seem sluggish,
but it was sluggish before the tune. And when gunned in the auto, it'll downshift for you and put
you into a gear that puts you in the best RPM's range..maybe 4k or so, where there's plenty of torque.

Myself, having the auto....the tune was well worth it, especially with the throttle lag elimination.
Andat the track...the car is 3-5 tenths quicker. Get some gears, that'll wake it up down low.

 

well.. if it were actually using the same amount of gas even though its getting less air then it would be running rich.. however.. since you have sensors to measure your air for you it will know to cut the amount of fuel to balance it I believe.. If you have a laptop you can do some data logging with your tuner that he sends you and you'll be able to see if its running rich or lean. actually.. you may not even need the laptop to do it.. I haven't played with it yet.. I was hoping to do it this weekend.

 

When going WOT I feel a burst of power at about 2500-3000RPM. I'm pretty sure it's normal to feel a little sluggish until the engine gets up to that point. Then again, I'm at over 3000 feet so who knows. Never drove the car @ sea level.
