HELL NO!

 

NOT recommended

 

just dont go over 10 pounds but you should expect spikes and boost creep and thats why its not recomended.

 

Downpipe and catback is ok...
dp/midpipe...

 

You can, but its better to be safe then sorry. I don't think you'll notice much difference of running 10lbs with just the down pipec vs. 10lbs with the dp/mp

 

thanks every one!!!! so how much i have to spend for
the ecu? which is cheap and good? thanks!!!

 

Apexi Power FC & Commander: ~$1000

 

Cheap+good=In your dreams! A power FC is all you need, and it isnt cheap (by my standords) but its well worth it.

 

Ehem, that's for USED. Add a few more hundred dollars for tuning.

 

yeah, but if he's already here, you'd figure he'd use the classifieds to try to find what he might need..... then again... people expect noobies to use the search function.....

tuning will cost about $300..... or so.....

 

thanks bro!!!! can i have some webside to check it out?
thank you very much!!

I could go on. Have fun reading.

 

Don't you just love those moments when you get to be like Mahjik?

 

lokrx7: Since you're in Frisco, check out Rick's Rotary Performance (http://www.ricksrotary.com/) out in Pleasanton. Rick will install and tune a new A'PEXi PowerFC for ~$1650.

 

why do you need to tune a PFC if your car is still ok for the stock map it comes with ?

 

Dude I have a 3 and 1/2inch downpipe, bonez high flow cat, and a evo Greedy cat back and my **** is running awsome, little overboost and a little rich but other than that it runs great lots more power. On the stock ecu.

 

I made 295 rwhp on 8lbs with intake, dpipe, midpipe, catcback and stock ecu with A:Fs below 10
But hey, you should probably listen to everyone who has only heard horror stories and never experimented.
Not trying to be an *** but it can be very safely done. Remove the factory boost pills and the car will only hit 8lbs boost. Either way the aftermarket ecu is a smart choice but not always necessary.

 

Talk to the guy operating the dyno. Its off

 

 

Why dont you do a search for my name and you will find the dyno sheets. There were atleast 2 guys off the forum there to witness it. But hey I knew most wouldnt believe. There was someone else a while back who made similar numbers with the pills pulled.

 

Sorry, but numbers dont add up.
Or your boost gauge is off or something.
There is no way you can make that much power at 8psi, let alone with AFRs as rich as 10.

Doesn't add up, thats all.
I've seen your dyno, but something must've been wrong. What is your 1/4mile time and trap speed on street tires ?

 

Unfortunately never ran the car so dont know. About 20 other cars dynoed that day and everything was fine. Wish I would have ran the car but never did.
