The problem I have with tuning is that I live in the Cayman Islands and there is nobody here that could (or trust) tune it for me. I would be willing to pay for someones airfare to tune it for me. Would they also need a dyno? We use to have one but they took it to Jamaica

Hopefully I can get it tuned & dyno'd soon since baseline should be somewhat similar in all 2SS M6's.

No video camera & only an Iphone for a camera so don't hold your breath. Sorry.

If the Mass air flow sensor is not in the correct spot on your aftermarket CAI system it will cause a check engine light. Come on by the shop and we will get you taken care of with a complete dyno tune. We will show you before and after results!

Although a dyno tune is preferable, you can work with one of the shops to tune your PCM based on your mods and ship it back to you. I think some are already offering a similar service.

You're on my list of people to call this morning.

Who knows of a tune shop in Houston?

i had long tubes on my WS6 and it had the Ls1 edit, and it threw the 02 sensor every once in a while. It might never go away. The worst case scenario is that its going to run rich and burn up your cats faster. The problem with the headers is that pretty much everything from the headers back is now going to VOID in your warranty, now when you throw in the tune your whole power train warranty could in a sense could be voided, but that comes with upgrading parts. Thats why I was going to wait 5 years until the warranty was up, im just not prepared to fork over dough in the first five years on the vehicle.

what code is it giving?

[Deltaskier]

I just went to Autozone to have the code read. They said something like 102 or 20something. Related to MAF sensor. I was chasing my daughter around so I wasn't really listening as I already figured it was related to the MAF.

It also seems to "buck"(maybe a backfire) every once in a while, when holding a steady throttle.

At least that narrows it down to the New Era CAI and not the headers...

[Deltaskier]

Went out to lunch today & the check engine light was out.

I know I'm not taking full advantage of the upgrades without the tune, but can't afford it right now. As long as the car is happy, I'll drive like that a bit.

Pretty pleased with the sound. Really didn't have enough seat time to tell if the car is quicker or not. It seems to wind up the RPMs much quicker so I guess that means I'm getting there quicker.

I hope to have some track times this weekend.

[Deltaskier]

Also, the new era CAI was a breeze to install. Headers were pretty easy as well but read the directions. My pass side manifold came out the top so I thought the header would slide in there too. OOPS. Kinda got stuck a little & scratched them up some. two extra bolts removed from the bottom & would have been no scratches & saved about 30 minutes.

Drivers side slid right down in there no problem.

[mlee]

Good deal... May just have taken a while to learn the new flow. I would really like to hear the headers or at least see them installed. It's one of the choices I have on the table for the next mod. Good to know about the passenger side too...

Are you going to make the Dyno session at LMR?

But yeah headers will throw codes because if you get long tubes or short tubes the distance between the two sensors change and the readings are thrown off. So you will have to get a tune to change that. if you dont want to get a tune which without one you wont get the most out of your upgrades, to you could buy the cheap 50 dollar code reader and just delete the code.

Long tubes ONLY affect the complete exhaust warranty back. If you change out your entire exhaust, does anyone really think GM would warranty someone else's exhaust or even their own if you have GM stuff AFTER the aftermarket stuff?

Nah...

Long tubes are fine. It won't affect the powertrain warranty. I've talked to numerous people about this...and this is why I went ahead and did long tubes instead of shorties to get the most I could out of the exhaust.

i got my check engine light at about 2,000 miles after my long trip back home. Stainless is working on a program/download to fix this issue. Before I download anything, I'm checking with my dealer and some GM folks first to make sure it does NOT affect or void the manufacturers warranty.

I KNOW that tuning the computer AFTER getting headers to get the most from the system will void the warranty....just ask the San Antonio ZR1 owner who tuned her LS9 only to throw a rod, needed a new engine, and got the pleasure of spending 21k on a new LS9. No thanks...I'm not touching anything like tunes or anything.

This is good to know. I was wondering about this option.

I could deal with that. That makes sense voiding the warranty from the headers back. I could deal with changing out cats until the warranty is up. Wouldn't want to mess the the PCM yet.
