Well I Finally Got Her Tuned

[mjdxtreme]

Well I got her back. Pretty happy with the results. I am shock to see what it was getting to the wheels before the tune. Here are the results. The tests were done on a dynojet.

 

Before:

264 hp at wheels, 280 ft/lb torque

 

After:

310 hp and 319 ft/lb torque.

 

Pretty happy with the out come, he only reduced the TM by 20% to be conservative. He wanted to make sure I would not have any problem down the road. I will get the actual dyno sheet posted once I get it scanned in.

Thats some nice numbers your puttin down.

[tjcbenz]

Who did your tune?

[mjdxtreme]

I had a local shop called sin city performance do the dyno tune.

[BuckFeverZ]

Not bad, not overly impressive though either.

almost 50 hp and 40 lb ft not impressive? then what's impressive?

[Spurshot]

I'm impressed. 50 hp from rearranging some electrons. No parts. Pretty cool.

I have to agree.

Nice, that is getting the most hp for your money. Didn't have to buy any parts, and still have stock reliability.

[Stex]

Nice, 40 ft/lb would help me a lot...wonder if BB gets that torque?

 

Not to rob thread, but did the new bulbs help the the dim low beam?

[VMax2007]

Adding a bunch of gay stickers like he did.

Maybe I missed it, but what engine do you have?

I have the 6.2L

Looking at the numbers on the Hypertech site, the stock 5.3 puts ~270 ft-lb and ~260 HP to the rear wheels.

They show 285 ft-lbs w/ their 87-octane "tune". So, (319 - 285)/285 = 12%. I guess I expected more of a difference than that w/ the 6.2, since the flywheel rated output is more like 25% higher. Those are impressive increases nonetheless.

I will agree. Impressive increases, but I am hoping that dyno reads really low. Otherwise you are losing 35% of your power through the drivetrain.

 

I have seen Vmax trucks with a 4sp dyno over 310 at the rearwheels.
