give me a couple months and i will let you know how a custum tune does in comparison. i wish christmas wasnt so close cause i would just order the sct now.

and i agree,the more mods you do the less than canned tune will benefit performance.

 

getting a used jetchip off a another forum user to see how it compares too. i am not going to keep it on my truck,i just want to see how the performance is.jet chip stage 2. i will let everyone know how it compares performance wise.

 

Aren't they supposed to work at first until your truck gets used to it? Therefore only testing it for a short time would pretty much make it seem like it worked well when in reality it may not.

 

i have heard some not so good things about the jet chip, so i donnt want to leave it on there very long. and i didnt know that the computer would learn it.

 

So, just for mpg you recommend Hypertech? Got one you want to sell me

 

sorry,already sold the hyper to another forum user.yep,so far it is the only mod that has actually improved my mpg. every other thing i have tried the mpg went down.

 

I am thinking of getting the flashpaq 3815 because of someone else's thread start...anyone out there that wants to yell at me not too?

If so please let me know why, thanks! They claim max 45 hp with my 5.9L...I don't believe it but I guess we will see!

 

i didnt get anywhere close to the 45hp claimed.i am thinking more like 20-25hp.just a guess,donnt have a dyno or anything.

the 3815 netted me the biggest hp gains on the butt dyno,compared to anything else i have did.

 

yea I just wonder if my exhaust would hinder it any way and my intake...from what I read it is best if you plan on stock condition motor...I've already changed my intake and minor exhaust but I plan on swapping out the tb and long tubes to either straight pipe or flowmaster super 44....hmm choices!

 

They say on their website that the Flashpaq will work just fine with other mods. They specifically list headers, a CAI (as long as stock MAF sensor is used), and a cat back system.

Basically, it is designed for a stock motor, so the more you do to the engine, the Flashpaq can't take full advantage of it. It doesn't necessarily mean it'll hurt it at all or that it won't work.
