So after replacing my worn fuel pump with a new unit, I went to the only Uprev tuner here for a dyno tune. I bought the Osiris Tuner version so changes can be made easily and hopefully I will learn to tune the G myself later on. Anyhow, the initial figures were pretty low compared to my last dyno run. I guess 110+F ambient temps and filthy intake filters did not help lol.

Before the Uprev tune, my baseline was 246whp. After a ~2 hour tuning session my final number came out to 266whp. That's a 20whp gain from peak-to-peak. Down low, the difference was anywhere from 20whp to 25whp throughout the powerband. No torque though since it wasn't showing up properly. I think it was around 230wtq when we checked.

My friend has a video which I'll put up when I get it.

 

By "baseline" do you mean with all your bolt-ons? 20hp for just a tune is crazy good. Looks like you had good gains throughout the rpm range!

 

yeah baseline is before tune with all the bolt-ons, so the 20whp gain is from tune only.

I'll do another run on the previous dyno I used for a better comparison. The one I tuned on had a slow as hell fan and it just read low on every car.

 

humm interesting.

How does the car drive? Does it feel faster?

 

Definitely! especially from a stop or low speeds. I can feel it slightly but at high speeds the needle moves faster. It now spins the tires through second gear when I was only used to do so on first gear before. It feels great, acceleration feels far smoother too.

Here's a video>>

 

Can you list out all your bolt-ons?

 

Not bad numbers dude! almost got the same mods as me! I got 280WHP and 241TQ with my dyno tune with the Cobb AP!

My Mods are Injen CAI, FI HFC's, and Stillen Cat back! But every dyno is diffrent, I know mines drives and runs harder than Stock. So it's not all about just the Numbers!

 

Mods are Stillen CBE, Injen CAI, Invidia HFC. They're listed above.

Yeah we got the same mods My previous baseline run on a proper dynojet (this one reads way too low for a DJ) was 260whp. so with a 20whp peak gain, that would put me to about 280whp like you LOL

 

#'s look good!

Man, i must be a granny driver. I've never been able to even break 1st loose unless the road is wet, or the car is on loose gravel.

... and i get 21.xx mpg on average.

 

I'll get a video spinning all the way through 2nd gear when i can
On wet roads i spun it through 4th gear at low speeds. So punch it from a stop, *wheels spin* hit the limiter, shift to 2nd, limiter still hitting, shift to 3rd, limiter hits again and then 4th. By the time i hit 4th i'd be doing maybe 40mph lol. oh and warning, don't attempt on public roads.

 

I've got to try that sometime. RWD AT's are a whole lot different when it comes to spinning the tires. FWD AT's are easier when it comes to this

 

yeah they are. it's scary though when u realize ur only going 40mph and the rear tires are spinning at over 120mph in 4th lol. I gotta try it again with the tune next winter

 

lol Q8y get a video up already

 

I need someone to film for me but all my friends are too damn busy. I need to buy a camera mount sometime and just do it all myself.

 

I'll pop over dude, what is like a 10hr drive? O.o I'll get the UpRev tune done as well ..................I wish
