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

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

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.....

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.

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.
