Well I got my HHR SS dyno'd this morning, I have the GMS1 tune and Trifecta tune both. 3 pulls

CF:SAE Smoothing:5

1st pull: GMS1 tune: 276/max power 282.27/max torque

2nd pull: Trifecta tune: 308.32/max power 336.57/max torque

3rd pull: Trifecta tune: 300.73/max power 337.27/max torque

Not sure why my torque seems lower then most, any ideas?

I feel if I would have done the Trifecta tune first instead of the GMS1 tune, I would have yielded between 310-315/max power. As you can see as I got heat soak and lost power between pull 2 to 3 BY the way I have the Dejon BOV spring that supposedly causes surge/flutter, looks pretty good to me.

 

I had recently tuned over the GM Stage tune on a Cobalt SS/TC with just exhaust mods. We did 314 WHP and 374 TQ.

Seriously, if you want a better tune....

 

Super!!!!!

NOTE: This tune is not the all out tune you can get. For most of the customers we have we explain this tune is suited for the ones that want the most power without major mods.

This tune takes advantage of max power in each gear that some look for.

The Infi-tune is for the serious mod and HP that want the max.

 

I know what I'm getting next!

 

I cant wait to get mine dynod

 

Got some Dyno logs?

Trifecta+warranty>HPT for now. Putting down what I did after driving 45 min to the dyno shop in 50 degree weather, driving straight onto the Dyno (I was running late and got there at the appt. time), with no cool down what so ever and making 308whp for my 1st Trifecta pull, but 2nd overall dyno pull is pretty damn good.

Next dyno session it will be straight Trifecta tune and I'll make sure to let the car cool down before the pulls.

Now if you can simulate the exact conditions I did on the cobalt and provide some dyno logs I'm all ears (or eyes in this case).

 

most hp tuned cars are putting down around the same power with a tune and downpipe only. also trifecta runs way too rich for my tastes, 12.0 on a di engine is too rich. I am tune only on my hhr and have increased my 3rd gear punch 60-100 by nearly 2.5 seconds and still have more work to be done. I cannot wait to get on a dyno, how's 3rd gear feel lol. I have just enough power to break traction around 55. I would like too see what kind of 60-100 numbers you could do with bolt ons, gmpp, and a trifecta tune in comparison. granted, its not too easy to find a nice flat road to get reall times.

 

oh yeah, all hpt cars I know going to the dealer havnt had any problems, including myself. just do a write entire and everyone has been fine.

 

Unless you show me dyno graph of a HHR SS with HPT, I don't really care what you have to say about a Cobalt SS/TC. I have yet to see a HHR SS with HPT make anywhere close to the numbers a Cobalt SS/TC with HPT does.

 

Show me a dyno graph and your mods list of your HHR SS. Thx
