So I got an I-speed ECU reflash...

i wonder if we can get a group buy?

You're basically tuning the car for something it doesn't have.



Oohh, okay. Thanks for clearing that up.. so then he would still have the same fuel cut.. it's only ours that change.

The OBX exhaust from headers back dosent have any cats. It just has two resonators that are made to look like cats.

Im going to post a picture of my RPM needle bouncing of the rev limiter at 6200.

Also I will post a pic of my new intake Im making that will have: cone filter, MAF sensor, and torque box.

Probably. How many people do you think we can get together? The more, the better.

Hey Supers, Took off the short ram and hooked the torque box back up, and I am totally amazed. Modded the box, borrowed the idea from SubySal except I didn't have enough pipe to make it a CAI, reset the ECU, test drove and the RPM's cut off at 6500. The intake got a lot quieter so I discovered an exhaust leak too. It seems like the RPM's drop a little slower but I think that might have something to do with an O2 sensor or two going bad. The car deffinatly pulls a lot harder. You should of seen the look of suprise on my face when I revved it passed 6k in the garage.

Long story short I speed reflash works and torque box works.

they dont tell you to use the stock torque box for nothing!!!! dont worry guys ill have some stories to post by wednesday hopefully when i get my ECU back form I-Speed!

Glad I could help KarateJoe

You know I was quite surprised too at the effects of modding the airbox. It's not my idea though. I got the idea from someone who used a 3" rubber elbow and a straight piece of aluminum pipe. I just switched out to an aluminum elbow to make the install easier and lighter.

Anyway yes I too noticed the intake quieted down quite a bit. It sounds more open like a full on race car. I also was surprised at the felt power gains. It was really noticeable at high rpm I thought, even more so than when I initially changed out the OE snorkel assembly to the PDM CAI pipe.

Your are going from a 2" to 3" opening though. A 50% increase in airflow is no small thing.

I for one believe the torque box should stay which is why I went through so much to keep it and make it work. I tend to favor the flat filters too. I think they create less turbulence. You know I've the RS filter is actually bigger than the WRX and STI filters. I'd say it could probably flow enough for a 5.0 liter V8. The reason I bring this up is because I switched back to paper filters after using a K&N for a while and finding some small particles getting though. I know the K&N's flow more, but paper actually filters better. So considering the over-sized filter and the dusty conditions where I live I went for maximum filtration.

thatreminds me, i really need to clean my filter!

[karatejoe]

Yeah maximum filtration is good. I have a MAF car so being that MAFs are so expensive I have a K&N cone, MAF, then 3'' pipe going to torque box w/ K&N filter in it.

I was able to snag some heat wrap insulation that they use for commercial hood system exhaust duct from work today. Once I get some more pipe I'll make it a CAI and wrap it with that and post up some pics.

Thanks again everybody for your help. This is the best site ever in my opinion.
