I just got HPTuners and I want to send my log to Allen over @ Nelson to tweak it out some. The truck just seems sluggish and slow. I wanted to post a log to have a few of you look it over and add any input you might notice. I realize that the turbo doesn't spool up till the 2k rpm range but would that still effect the low range compared to stock? It just seems to be bogging in daily driving. The throttle response when it was stock was instant and crisp. I have upgraded a few things since Nelson tune:

TR6 plugs (.32 -.35 gap)
Walbro 255 Fuel pump
160* Thermo
TRT FMIC

I did just a basic log but any input would be helpful.

 

send me your STS kit and i will try it out on my truck for free to make sure it isnt faulty

 

Can I include the wife in that package?

 

OUCH

 

Logging maf freq would help Allen tune I bet.
And your LTFT are pulling A TON of fuel....

 

Thanks, I forgot to mention that MPG has dropped to 11 or 12 miles per gallon on the Highway. I didn't have the fuel pump in back when allen originally tuned it. I'm also running 10 lbs of boost.

 

Sounds like you need a retune? It might be that your getting toooooo much fuel which could cause the sluggishness? Just taking a stabb at it.

 

Wilde Racing and 04GIBBS are all over it! Get some MAF data and your NBO2's don't go under 930mv's when you go into PE. Pouring fuel on those CATs LOL. You may even have an ounce of rich knock in there as well.

SInce you have HPT, and if you aren't planning on going 2bar, familarize yourself with the steps needed to nail down your VE then your MAF. If you are running 10#s, you may consider 2bar down the road. But for now, get your ve/maf inline so you can command god numbers.

Now that you are FI...GET A WIDEBAND and cut the frustrations of tuning this pig in half!!!!

 

WOW some of that was sooooo over my head my man .

You are talking about the actual info in the tune huh?

 

Do you thing that the cats could be clogging up over the last 5 months of running this way?
