My exhaust is stock back to the borla dual. I'm thinking about the CXRacing cat back 3". Its the only cat back system i've seen.

The nocking is some sort of emision control. It is a vacuum line going from an electric control to the throttle body. The electric control is creating some sort of pulse in the vacuum line going to the TB. If I disconect the electric harness to the control the nocking goes away and the idle smooths out. Otherwise the idle bounces from 600 to 900.

I've ordered an elmscan5 and scanXL software. Soon to be logging the FIC and the ECU. Now for more education in the field of tuning.

The car is a blast. Quick off the line and plenty of power for passing on two lane black top. Its great to blow by someone trying to play road games, speeding up for passing zones. I hate people that speed up for passing zones, now I just laugh as the speedo clicks into tripple digits.

I need a radar detector more than any thing to make the car faster.

The CXR cat-back is probably the best flowing option available but I've read about some fitment issues. You might want to search that. I've seen a lot of favorable reviews of the cheap ebay s-pipe-back but it's only 2.25-2.5" dia. I believe you could use the WR S-pipe with it. I'm not sure what I'm gonna do yet. I'd like to go 2.5" all the way back with a hi-flow cat and keep my TRD AB.

That emission control is the vacuum switching valve assembly and is part of the evaporative control system. AFAIK it basically sucks gas vapors from the fuel tank into the TB. Originally I tee'd into that line for my boost gauge and BPV but later tee'd into the brake booster line and added a vacuum block. Because of it's evap function, I don't think it's a reliable vacuum source for gauges, etc.

The Elmscan5 is an excellent OBD interface and IMO ScanXL is great OBD software for it's price. I wish ScanXL was easier to use but I'm learning it. It's very customizable, which is good, but it takes some time to figure out how to set it up.

I absolutely HATE those imbeciles who putt along at 45 in a 55 and then speed up to 65 at every passing zone. Worse yet are the morons who floor it when they see you moving over to pass them. It's so nice to just zip by those pathetic losers despite their best efforts to kill me. Speaking of triple digits, I haven't gone past 120 yet and was wondering when the speed limiter kicks in? Any idea?

Enjoy the booooost.

Just finished a 4300 mile road trip through the northwest. Car ran great. Still getting an error code for high voltage on the #2 o2 senson and random cylinder misfires. The random cylinder misfire code didn't occure when running the 92 octane they sell in washington and oregon, lucky bastards. I quess im stuck with adding octane boost. I'm wondering if the cel eliminator i installed when runnning a header might be causing a problem now that I have a cat?

Removing the cel eliminator worked. And adding 8oz of 108 turbo ocatane boost has taken care of the misfires. Its nice to drive without that flashing yellow light.

Can I use my obd-II scaner to turn of the maintenance light? I have the elm scan 5 and scanxl software.

On a final note, I beat up on my first mustange today. He must of just had the stickers and not the parts.

That kit looks awesome its just so hard for me to get over that intercooler. I might have thought about it but now that I just put 8 G's into paint I dont think I would have the guts lol.

Love the kit thought. I can tell a lot of time and effort has gone into it! Im glad somebody finally picked up the ball for us gen 2 guys. Do you guys have a Gen 2 that I can see close up at your shop? I drive out to Torrence almost every weekend.

For the turboed guys - what kind of city and highway fuel economy are you seeing?

100% highway 55-65 mph speed limit 25.5mpg (average 70mph)
100% highway 75 mph speed limit 24.0 mpg (average 80-90mph)
100% city casual driving 20 mpg
100% WOT 10-20gph approximately, untill the tires explode.
I actually tracked my mpg on a long trip so the highway numbers are fairly acurate. The WOT numbers are an estimate, but you can about watch the gas needle move when you hold the pedal to the floor.
