Hahn BSR tuner for 2008 model year vehicles

Hahn Sales · 10-05-2007, 11:56 AM

We have received and seen forum feedback regarding the performance of the BSR tuner for 2008 model year GXP and Redlines. The talk has centered around the inability of the tuner to program the ECM properly on some applications. This can occasionally be the nature of ECM calibrations on new model year vehicles. Software changes come at the manufacturing level at any time and tuners may be unaware of newer ECM software calibrations until tuning is attempted.

This is to inform all 2008 vehicle owners who have purchased the Hahn BSR tuner for their vehicle that Hahn RaceCraft is working closely with BSR to craft a solution for their non-tuning conditions. Hahn RaceCraft will be in personal contact with all such customers to discuss their needs.

Any update on this yet? Still sitting here with a $1000 PPC tuner that doesn't do anything.........

Yeah, can't wait 'till you've got it ready....I got the call yesterday that my '08 RL is on the way to the dealer for me to pick up.

OK, BSR sent me a new tune that works on my automatic 2008 Sky!!

I took the car out and punched it.....the boost guage went up to 24 psi immediately and stayed there through 1st gear. WOW! It was weird to feel it pulling as hard as it did after it went up above 18 psi, where it normally stops.....

Not sure if this is normal or not, but when it gets about 1/2 way through 2nd gear, it drops back down to 16-17 psi and won't go higher.

I noticed that after two hard runs, the computer shut off the turbo and it wouldn't go over 2 psi until I turned the car off and back on....then it would hit 24 psi again.

Perhaps the intercooler is inadequate for the increased temperatures from the increased boost level?? Does the computer need some time to adjust to the new programming??? Maybe I need a bigger intercooler??

That's no good, contact BSR... or whoever gave you the tune. and dont keep "punching it" till you hear from them.

I had the same thing happen to me but my car is stock and manual trans. I punched it in first and shortly after i hit second the car lost all power. I had to turn it off and restart to get it to run right. So maybe it isnt the BSR but who knows, i just thought i would mention my experience.

2thDr · 11-06-2007, 08:40 PM

Problem seems to be solved. I took my K&N air filter out of the car and replaced the stock air filter. The car did numerous full throttle runs without shutting the turbo down like it did yesterday. It even hit 25 psi on the boost guage once. It seems to hold around 21-22 psi pretty consistently up until 4800 rpms or so.

Wow......it sounds like it's worth every penny on the BSR Tune. I can't wait to get mine but I think I need to start with the exhaust, CAI and IC first before the BSR Tune. Thanks for the feedback and have fun.

Welcome to the forum!!! Thanks for adding your experience. Every little bit if info helps.

lostcause · 11-06-2007, 09:59 PM

I hate to beat a dying horse but does anyone, anyone at all, have any clue what boosting this tiny turbo to 25psi will do for its lifespan? From all I have read, the rest of the internals are built to take a lot more power but the turbo seems like it might be too small to push that hard.

BlueSkyRL · 11-06-2007, 10:09 PM

How did you know that the K&N filter was the problem????

Rob the Elder · 11-07-2007, 10:23 AM

What is the temp doing when you are at high boost? The internal pressures are getting pretty darned high at that level of boost. I suspect that the current state of tune from the factory is related to the 100,000 mile warranty as much as anything. I also suspect but do not know that if you have a heat related failure in the motor the factory will want to void the warranty because of "excessive boost" . Anyone have any knowledge or experience in this area?

BSR suggested it. They said to use the stock air filter.

BSR told me their tunes are designed for a completely stock Sky. I asked if I would need my tune altered if I installed a larger intercooler or changed the air filter back to a K&N. They responded "We do not do custom tunes."

GeniusInABottle · 11-08-2007, 10:32 AM

How can you get this new tune? I have a 2008 auto sky redline as well.

lostcause · 11-08-2007, 10:39 AM

I'd love to get this tune also but I'll reiterate the question I asked earlier. Does anyone, anyone at all, have any clue what the long term effects will be from boosting this tiny turbo to 25psi?

GeniusInABottle · 11-08-2007, 01:48 PM

I thought it was pretty obvious that (over)boosting the turbo would shorten it's lifespan. I think the real question is, by just how much? And that I don't think anyone knows yet.

Why don't you call Hahn racecraft and ask them this question?

Not that I don't trust them but do you really think the vendor is going to tell you that his product will kill your turbo? That said, I do realize that they aren't going to sell something that they think will damage your car, but since they aren't the ones who developed this tune and are only reselling it, do you even think they will know whether it will cause damage? I'm sure if it were found that it did damage the car they would probably stop selling it, but I guess what I'm getting at is that they aren't a reliable source for this type of info at the moment.

How about finding parts of the lower crank like rods and such, coming to visit you in the Sky seats .....Skip....

Oh and they will bring their friend, engine block parts, to say hi as well...

heh.

Seriously though, haven't some GM engineers been quoted as saying that the internals are rated to at least 400hp?
