ADR ... some loss TQ & ALL CARS REACT Differently.
Id lost more then 18TQ but my TUNER got it all back for me.
Just right down ur numbers & u'll really see ur leaving some TQ & HP out by not getting ur car tuned.
U can see its apperent from 2500RPM with out the Xpipe ur already at
420 - 425TQ VS with the X-pipe at the same 2500RPM ur only at 400TQ.
Tuner couldnt get me more then 17HP on the peak side but with the new Burn he got my TQ & Some.
Good Luck.

U really want that 500HP mark dont you? :beer: same thing with me.
Even if u let the car cycle a few times i dont think u will see any gain of 25tq from 2500rpm that ud lost with out a tune....Are u still not going to run a new burn with the LT & TB?
Oh did u got to Carlsbad yesturday? Wish ud make a thread on it at the TIME SLIP BAR.

Yeah I want to get close to that 500 at least. I will get a reburn after adding those mods. No I didn't go to Carlsbad wish I had, I heard it only drizzled and then dried up, when I left the Dyno shop it started raining so I didn't go, now I have to wait two weeks to go because I have stuff planned for the next 2 Saturdays.
low torque numbers could have been from the air if you said once you left the dyno, it started raining...just an idea
You guys are making me not want to install this xpipe I have sitting here!
Your car is running way too lean! 12.5 to 13.0 from 4k to 6.5k is NOT safe at all! You need to be running in the 11.5 range. It's time for you to get a reburn, and fast, or you'll find yourself with a melted piston, broke valve from a fried plug, or worse, a snapped rod through the side of the block!
I agree the stock catback is probably the biggest restriction. I put down 456 with stock exhaust just with the stock mufflers hacked out and straightpipes installed.
Makes me think twice about going with an X..might have to hold off and go with a good catback.

You are right about the A/F, I looked at my numbers right after getting the Chip and the A/F is around 11.5, but my tune was done on a different dyno, I have heard about the A/F creeping back up like that or do you think its from the X-pipe although the Dyno i did without it has the same lean A/F readings. I will go to the Dyno that it got tuned on and see what the A/F reading is on there. That would be a good thred, so would the A/F reading differ from one machine to the next?

Yeah, they can vary greatly from one to the other. Before your X-Pipe your 2nd graph was showing mid 12's constant up top, now you're upper 12's after the X-Pipe. I just wouldn't trust anything but a real wideband. Why don't you go to www.widebando2.com and pick yourself up an FJO! www.fjoinc.com for more info. I have one, use it and the datalogging kit, and it works great! It showed me that the Dynojet here is a full 1 to 1.5 points showing LEANER than the FJO when comparing on my Cobra! Now that is scary to think about when it comes time to tune. On Lightnings the Dynojet normally shows dead on or w/in a few tenths to the lean side versus the FJO. This isn't indicative of all Dynojet's meters, however, as I've seen some that are dead on when on a Cobra. Something about this one here tho :-\

Sigh, put on my xpipe and it sounds like a honda with a fartcan now unless im at WOT
Think i might try to find a good aftermarkey H.
Anyone tried this?

Only stainless steel one I was able to find, brand new and supposedly bolts str8 on to a 03 cobra.

You sure its sealed, when he first started mine it sounded like a V6, and he said one of the sides were not sealing, mine sounds the same just a little higher pitch. I need to have my wife drive it around the block so I can hear it from the outside, maybe headers will help?

Shrug, Ill check, I don't have a lift so I have to take it back to the shop, but this sounds really bad
Not planning in doing headers bc the dealership wont let me if I want to keep my warranty, and I do want to keep the warranty for at least a year or 2.Its plenty loud and all but good lord, after the H + Magnaflow catback, this X + Magnaflow catback sounds horrible
Prolly just gonna put the stock H back on tomorrow and sell the X pipe on EBAY if theres no exhaust leasts causing this, and spend the money on a Steeda CAI instead (My goal is just 400rwhp without voiding warranty).
