GIAC vs JB3

YngPhllyKd · 01-11-2010, 03:43 PM

Alright...before anyone jumps down my throat about searching and this being a big topic...i just need some help and quick. I did some searching...and read great reviews about both GIAC and JB3. I had an appointment this morning, that i cancelled, for the GIAC reflash. The guy told me that the reflash only puts up about 50hp to the crank...which immediately made me not want to get this.
What kind of gains should i expect on a stock car with JUST the tune? lets say GIAC stage 1 and JB3 (Map 3 & Map 5). Thanks for your help guys...I plan on making a decision by tomorrow so any help would be appreicated!

Tune and at least an upgraded FMIC go hand in hand. Why make your turbos work harder with more boost without letting it breathe?

But hey, its your car.

BTW: if you go with GIAC and don't like it, you can't resell it (after 30 days). With the JB3 you could take it off and resell it.

If you are completely stock you can compaire GIAC Stage 1 to JB3 map 3 since boost is the same.
Map 5 will probably yield a bit more than GIAC stage 1 .
Consider however that its also important how the power is delivered.

What's the approximate WHP gain with GIAC stage 1 and JB3 Map 3?

It's easy to order a JB3 1.4 and give it a try, you'll be impressed. Not just by the power, but that you can easily install and remove at home. Some report the GIAC is a little smoother, but the JB3 2.0 addresses that, and will be a free chip update. They are testing now, so maybe a couple months out before full production?

This really comes down to your preference and what you expect from a tune/flash/modificatin. GIAC is a reflash that has been extensively tested and is a proven reflash. JB and PROced are also good piggybacks but by the natune of piggybacks, they have less control over how the car drives and to take that control, it takes alot more research since they mostly play and intercept sensor signals to ECU. Reflash on the other hand has by nature much more control over the values at every RPM and intercepting the signals are not required. Hence, the different driving characteristics.

Another important thing to remember as well is that most of us car crazy people, go through phases where we don't care how the power is delivered as long as it is delievered and we want as much of it as possible. We also go through phases where we do care about the power delivery and drivability of our cars. depending on which phase you maybe today/this month/this time, your purchasing and decision making process will be different regarding to which tune/flash regardless of any of them being better than the other. Your definition of better is changing over time.

I suggest you read the reviews, try to take a ride in cars with similar mods and see for yourself.

i got 310 whp on jb3 map3 completely stock.

I had GIAC Stage 1 but i was fully modded and got out 335 whp.

My stock run was 250 whp and fully modded on stock ECU 272 whp.

supracg · 01-11-2010, 05:12 PM

I think the OP is looking for the whp differences: lets say whp delta with map 3, 5, and giac stage 1.

OP just keep in mind that feel/smoothness is the other aspect that should be considered with a tune. If your not really worried about that, then once you get the above values your decision should be pretty easy.

EDIT: enrita got it i think

Took a quick look...going to check it out in detail later on. Thanks for this!

NRG · 01-11-2010, 07:19 PM

GIAC S1 compares to JB3 MAP5 boost wise and power on a stock car (mine at least). GIAC ability to laydown and distribute that power across the RPM in every gear is beyond anything I've tried/had and I had a few...

Nicely worded

It does appear, however, based on prelim reports about the N55 vs. N54 that the good ol' N54 was/could have been built for even more power than it typically delivers in stock form... meaning that whatever boost produces 400 or so hp won't tear the engine into smaller pieces. The trick is to get the turbos spooled up fast enough to deliver this power quickly.

I am sorry but some of this is just outdated thinking. It would be like saying the earth is flat. You know some people used to believe that but that caveman thinking is of old. The new piggybacks are more advanced than they have ever been. The smoothness and power delivery is incredible. You can change maps on the fly. You can remove it on your own before a service visit. Finally if you choose to run methanol you don't have to hope you ignition retards enough to save your engine in the case of a methanol failure.

Flashes have advantages, but so do piggybacks.

I keep hearing great things about the giac flash and its smoothness. Can anyone tell me how this compares with the dinan stage 2 flash interms of smoothness? - please no flaming about dinan costing 100xmore blah,blah

SIEN · 01-12-2010, 07:37 AM

I think most flashes you'll try will be ultra-smooth... they are after all editing the base values of the DME itself so they should be.

(Saying that the latest versions of the piggybacks have come such a long way that they are pretty much on par)

Zeph · 01-12-2010, 08:26 AM

If you want a higher dyno reading then JB3 will have that potential over GIAC stage 1. Either way get an FMIC to keep the temps down and help out your turbos' longevity. You will be happy with either tune.

A JB3 tuned car did just set a record

Can't decide between GIAC and JB3? Get a Procede v4

LOL! I did my best and managed to narrow it down to GIAC and JB3. These 2 seem to be the most efficient tunes...but to each their own i guess. Still cant decide...ahhhh!!!!

Sniz · 01-12-2010, 10:51 AM

If I was to get into another n54 powered vehicle it would be tuned w a GIAC reflash and meth.

SIEN · 01-12-2010, 11:04 AM

It's great that all of the options now available don't have any significant downsides! There is something for everyone, so whatever you buy you'll be happy with!

Drive a v4 car. This is an honest suggestion. It's profoundly different that any other tune out there as more people will see this week.
