Clearly, somewhere, I missed something! Axlehead, I didn't know you connected the Gryphon to Pegasus without returning your truck to stock first. Somewhere, my feeble old brain remembers that Bill has upgraded Pegasus so it won't work with your unit unless it HAS been returned to stock? But, in your case, it did, since you were able to update the splash screen.

Possibly, just possibly, updating the splash screen is not quite like updating firmware - in fact I'll bet that's the case. I'm betting your stock tune is still there and everything is fine, but -

In the future, return the Gryphon to stock before connecting it to your PC, and

DO NOT return the truck to stock for an emissions inspection! That's an almost certain way to get a failure unless you put your truck through enough drive cycles to get rid of codes the set back to stock creates. Just take your truck to the emissions station with your current tune set in. Everything I've read on this says the only people who fail are the ones who DO set their trucks back to stock before the test!

If it will make you any more comfortable, simply remove the Gryphon and tuck the OBDII cable up out of sight before you take it to emissions, so they won't have a reason to question you. That's what I plan to do.

Ok so as far as emissions go will the custom tune I have ordered be ok for the testing or not? That was why I wanted the stock tune, since California has strict requirements.

EVERY post I have read that talked about having their trucks tested with a "tune" installed has said it passed with flying colors! My truck has not been required to be tested yet, but when it does, I WILL NOT put it back to stock before the test! (And, some of the posts, sorry, I don't know how many, were from people in California).

But, EVERY post I read that talked about setting their truck back to stock before the test, reported a "failure"! This is because of codes in other components that have to go through "drive cycles".

so I sent my hex code via pm and email about a week ago, but havent got any response. I just want to make sure that the info was received. Its gonna be a long 4-8 weeks! :drool2:

If you don't think they got it try again they had a busy weekend.

Another place to put the gryphon info is in this forums user cp. Go in there and put the hex code in and serial number in.

Yes! DO put it there! Bill and Corey look there first for this information if they can't tell what it is from your "posts" or emails.

If you already haven't, add your first and last name to your UserCP (it can only be seen by Bill or Corey). With the many new members this site is getting, it makes it difficult for Bill and Corey to connect the forum nickname to the person.

does anyone know if it is possible to run the CAI with the tranny tune? I only ask since the tune doesn't do anything to engine. Just a thought since I figured it would be no different then running stock with CAI. Also does anyone know if my 03 model year truck has a lean problem with the CAI? I have been told this primarily effects 05+ models. I'd like to continue with the performance tune but gas is getting back up there and I am not sure how the tow tune is as far as a daily driver. Thats why I am considering doing the tranny tune.

Sure, you could use the tranny tune with the CAI - as you said, it's pretty much like the stock tune as far as the engine is concerned.

But, before I got my 87 non-tow tune, I used my custom tow tune (and before that, the canned tow tune) as the daily driver. It was fine as far as I was concerned.

well I know its ok to use the cai with the tow tune, but which would be better as far as mileage goes? tranny or tow tune? Thanks.
