I ordered my tune!!!!
Do you guys think I will see a difference in power and shift firmness?
Also, Do you think it will be a problem that I did not fill in the box for "PCM Service Code", I dont have any tools at my house and I couldnt see the code without it being out of the engine bay!!!
As for the 2nd question, i have no idea what your talking about?
Anyway, IIRC you haven't even tuned for your 4.10 gears so the speedo and shift points have been way off. If so, then I think you should feel a difference, especially with CAI and LT headers, going from stock tune. If not, then something's wrong. True, with a stock setup you might not be able to "feel" the difference, but you should pick up a couple tenths in the 1/4 and a couple mpg's. Should be more significant in your case, since your a little better than stock.
My speedo was off by about 10mph low, so 40mph, I was at 30mph...
To try and clear up the confusion on my last question: In the tuning sheet he has you fill out, it says Specify the ECM/PCM/ Code on your module?

Then I cammed it and had it tuned again, cant comment on gained power since I didnt drive the car untuned but it made it idle so much nicer
yes its gonna start with the new PCM. lol How do you think he stays in business? I just had lt headers when i got the tune from him along with deleting some codes. I later had it switched to a local guy who went over everything. Madz28 tune wasnt anything special and it was pretty close to stock to be honest even when i had him re-do it when i first installed the hotcam. Very little was changed. sorry to burst your bubble like that but im just telling it how it is. Have fun

i think what the code thing means is if you want specific SES codes deleted from your car such as EGR or the rear o2 sensor codes. stuff like that
Is there anyway I can keep my tune and just have the gears recalibrated, codes deleted, etc...?
I dont think there is since I'd be getting a new pcm, PLEASE LET ME KNOW ASAP... So i can email MadZ28
Juar email him and tell him the situation. its just him that runs the business out of his apartment. its not like hes some huge company

He said his tune would make the same power if not more and it would have all the bells and whistles I asked for.
