when i tune my truck to the hi performance setting for the first time it was very very noticable improvement. now a month later it seems not to be as powerful, so i set the truck back to stock and reprogrammed to hi performance and it still does the same thing not like the first time i programmed it. the only mods to the truck are an mbrp 4" stainless steel exhaust from the turbo back and i am not running the cat i have the test pipe in. also put the air raid filter box on. just cant figure why the loss of power.

 

What Tuner do you have and year truck?

 

it is a 06 f350 superchips micro tunner

 

shamrock442, I have the same feeling with mine as well. I hope someone can tell us what has happened.

 

for certain but from experience it seems to gain memory of my driving habits. If I run it hard for a while or a few times in a row it will seem to stay very noticeable. If I am just driving to the office and playing innocent it seems to have the effects you are talking about not sluggish but less noticeable power when I do get on it pretty hard.

 

Thats your problem Supercrap micro tunner.

 

Get a life, buddy.

I'm tired of your flames.

Shamrock:

Honestly, you are probably growing accustomed to it.
When I had an 03 cobra, it felt fast stock, then when I upped it to 472 RWHP, it felt REALLY fast.

After awhile, I was bored and swore the car was down on power, so I strapped it to the dyno..power was still there.
Track #'s were still there.
It was all psychology. I was used to the power.
I sold the car and my friend upped it to almost 600 RWHP, which feels blindingly fast, but some people get bored with that, too.

I'm not saying you don't have a problem at all, I'm just saying that it's likely you are getting used to the power and growing "numb" to it.

It's a very common phenomena, until you go back to stock and realize just how slow it used to be =o)


Also, remember that the transmission is adaptive, so SOME (not all) transmission parameters need a learning curve regardless of whether or not they have been recently flashed to a new program.

In the early stages of tuning, some trucks adapted a very harsh shift, which went away only after being set to stock AND being driven some miles over a day or two.

Can you give a little more information on when and how the problem is occuuring and what happens when you return to stock?

 

Thats funny Vic Why don't the guys with the SCT custom programs say that. I thought you didn't work for SuperCrap anymore. Still loyal tho uhh. There are to many programmers out there better than SCMT and I wouldn't settle for that reason alone.
