Oh no, ANOTHER chip thread.
Okay, the time is here.
I just ordered my vent boost gauge and a new DV so I think I'm ready for a chip. The car is running great and I have the new clutch broken in well.
Being in Kansas City I have two choices.
GIAC
or
APR
Imagine Auto does GIAC
Imagineauto.com
Bob Hindson Racing does APR.
bobhindsonracinginc.com
Now, with that said I'm wanting obviously the best reliability and best perfomance. From reading dyno charts off GIAC and APR's webpages I'm seeing these results:
GIAC: 182hp and 206tq
APR: 209hp and 245tq
Am I missing something here or reading something wrong? That's a big jump..
I see all these guys going with GIAC but I'm not sure why.
I hope this thread doesn't flop, this could be an aid to all the other noobs like myself who need to know the details behind these chips and what the REAL WORLD results are.
A couple things I'm curious about
What are the REAL wheel HP numbers on a stock TT with a 91 programed APR or GIAC ECU.
What company do YOU have or reccomend. And... do you have any information I need to know before I dive into this on tuesday?
You guys have been amazing help so far, thanks again!

im no expert...
but i think you might be comparing crank hp numbers to wheel. giac being wheel and apr being crank.
i went with giac 93 program because people i know said it was a more agressive programing. replace your maf with a good oem maf before the chip (found that to be a problem in my situation). i spike 24-25 w/o BM & hold 20
i think they are all simmilar software. but as i said, im no expert

well...
from everything I've read and seen, APR seems to have a better base programming map as far as fuel and timing. GIAC seems to throw more boost at it to get the gain. With the fuel available in the area, you are stuck with a 91 oct program. If you get the APR you can dial the boost up with a boost machine and add even more power. The same can be done on the GIAC, but I'm not sure the gains will be as significant.

I've had both and here's my butt dyno/personal opinion (couch mechanic) response:
APR is smooth, more linear and not as fun to drive...
GIAC has a less refined 'edge' to it... feels like you have a mod worth the money you've spent, and kicks in just a bit more sharply than APR.
Note: I had GIAC first and for a bunch of reasons (mostly 'grass is greener' stuff), I switched to APR. I had two major issues with the programming and workmanship of the APR switchover. Kinda left a bad taste in my mouth, but nevertheless, many people here swar by APR.
Were I to do it all over again, I'd stick with the rawness of GIAC and not have done the switch.
My $0.02...

I have APR. I had problems initally, but APR customer support was very good. APR is more
Mod friendly. If you are planning on ModShack stage II or stage III, then APR is a good bet. If you plan only the chip, lots of happy GIAC owners out there.
FWIW, I blew out my MAF and DV within minutes of reprogramming. The tip about the new/remanufactured MAF install would have served me well.
It is important to know that there is cause and effect with your power plant. Take that into consideration when you chip.

GIAC >>>
I have GIAC 91 and am happy. Lots of folks happy with APR as you can see.
FWIW the place where I had the programming done is a GIAC and APR dealer and couldn't say enough nice things about GIAC's customer service. In fact, there was a minor issue loading the software and the dealer literally called Garrett with GIAC from the shop floor (I think he's the owner) and worked through the issue.
That being said, I think you can't go wrong with either...

APR has been good for me
started out with one of their specials...buy one get one free. Been adding on at each event Ive gone to with them as Sponsers. Now have stock, 91, 93, and 100 for less than $600.
Love the speed stalk programing, but usally stay with the 93 or stock when going to the Dealer for service, 91 seems MUCH tamer than 93 and Ive never used the 100. Cant seem to find the gas in western NC where its either 87, 89, or 93 at the pump. Just my 2 cents BTW they are really easy to deal with, as was my original dealer GMP. Good luck!<ul><li><a href="http://www.gmpperformance.com/">http://www.gmpperformance.com/</a</li></ul>

My suggestion: Forget the chip and reprogram your computer with REVO
Ask them to recommend a dealer or find one here on the forum. Either take your car in or send the ECU to them. I sent mine in and it was turned around in less than a week. No problems, no issues, nothing but one hell of a lot of low end torque and loads of power.
Either buy one of the available, optional Serial Port Switches or borrow one from a friend. Then you can play and tweak the thing to your hearts content.<ul><li><a href="http://www.revotechnik.com/index.aspx">REVO Technik</a></li></ul>
