OK

I see a lot of people posting with questions about ECU flashes. Heck I was one of them a few months ago when I got my Injen intake. The answer is yes you need one. If for no other reason than gas mileage get a flash. When I installed my intake I felt like I lost a bit of power and my gas mileage was terrible. I got my ECU flahsed, installed a full 3" exhaust and now I have a lot more power (a lot meaning this car is fast) and I am getting about 80 miles more per tank of gas. The flash will pay for itself in a few months. So get a boost gauge and get an ecu flash. Those mods combined with a turbo back exhaust, fuel pump, and boost controller are an incredible combination. There are not many cars that you can spend $2,000.00 (or less) on and get 70 hp.

I hope this helps a newbie like me that was/is wondering if they really need to get the ECU flashed.

which flash did you go with? did it get rid of the boost taper?

 

$2000 dollars gets you a bit further than 70 hp. Glad to hear that your flash went well and that the car is performing like it should.

 

but wouldn't a flash void our warranty? am really eager to do it for added hp and better mpg but worried about warranty issues

 

the dealership wouldnt have a clue.

 

Yeah , I agree. look at this:

$399 for a LPI 3" cat-back from Logic Performance
CAI for less than $99 or drop on for about $40
$99 mail in flash
$139 Downpipe from Logic performance
$90 fuel pump
$50 boost controller
$199 headers from gruppe -s

So for less than have of what you mentioned we can get much more power compared to your $2000..

 

$99 mail in flash? where is that?

 

you can get a great (BEST) mail inflash from dynoflash.com but its 200bucks

 

so Jin, did u get a flash yet? do u have an 05?

 

I had a flash on my 03 couple months ago but now that car is sold, and im planning to do a tune for my 05 after it breaks in.

 

i think i read here somewhere that the dealer do detect if the 05 had been flashed or not, hence, voided warranty...is this true? coz i really want a flash but am worried about this issue....

 

Wrong, they can detect flashes on 05s.

 

You're warranty was voided when you left the dealership

 

i was thinking of the 03 but was not sure about the 05
