injen intake and FI exhaust

Should i seriously see a 30 HP increase if i were to put in the injen intake, FI catback and highflow cat? I want to believe this but for some reason im a little bit skeptical, i have tried searching for 3rd party dyno's of both but have only found a few seeing how they are both fairly new, especially the injen.

Anyway how much should i trust these numbers im seeing from the FI and the injen?

no one has a dyno of everything put together yet... but 30 may be on the high side.

^^That statement is totally correct. I have the FI Exhaust/FI HFC's. I posted a thread for the redo dyno, and once the injens go on I will be dynoin again. SO we'll see what kind of gains there is going to be.

I want to see you do an ecu reflash and break 50+ HP with all your mods. Do you think that is doable when the ecu reflash becomes available?

i suppose my next question is, are these 2 items both on back order or whatever? or would i be able to immediately buy them when i want to? because iv read a lot of threads saying that there are a lot of people on a list that need to be shipped to before others can start buying.

I believe 50whp is doable, the exhaust system on these cars are incredibly restrictive. I think someone mentioned the stock piping is only 1.7" and a lot of times car manufactures use 2" OEM. Open that up a bit to 2.25 - 2.5" and you'll make very good gains.

With all those mods, the AFR will be slightly lean on the stock ECU. A reflash would be highly recommended to get the most from the bolt ons.
