I am looking for some input from SS/TC owners with tunes. Everyone is wondering about aftermarket tunes and such for the TC so I figured I would try to get as much input as possible on your tuned cars. If you have time answer the following questions, so us "non tuned" drivers can see if we want to make the switch to the "dark side".

1.Mileage (Total miles on car, not MPG's)
2.Estimated Mileage since tune (ditto)
3.List of Modifications (Engine mods only)
4.Type of Tune
5.Dyno Results(How much HP and TQ you gained from stock, not just the numbers)
6.Problems with Car Since Tune
7.Aggressive Driving (Use a scale of 1-10, 10 being you WOT every chance you get, and 1 being your pedal has never reached the floor board)
7.Anything else you would care to share.

I know it's somewhat long, but I think a lot (including myself) of TC owners arent getting tuned because of possible engine failure, CEL codes, etc. And a lot don't want to jeopardize their warranty. But if the non tuned owners get enough feedback, they can better decide if it's worth the risk. Thanks.

 

1.Mileage: ~11000
2.Estimated Mileage since tune: ~500
3.Mods: Currently stock w/tune
4.HPTuners by SMG Autosports
5.Don't have my sheets, somewhere around +55whp, 80+tq
6.No problems with the car
7.Aggressive Driving: 4 Its my DD, but I get on it when the opportunity but not very often at the moment

Plain and simple, you will absolutely love a tune. I thought it was great before, but its amazing now. I got a unique deal, so I said screw it and didn't worry about the warranty. You only live once, thats my motto...

^^ thats on a heart breaker dyno too. Stock for you was around 220 right??? most people Are seeing 240's stock.

 

with the HPT, can you set the car back to stock so the dealer will still give you warrenty? Because I know with intake exhaust intercooler charge piping, you can bring that straight to the dealership and they have to still value warrenty. This is because of the magnuson vs moss act. Computer however, will destroy warrenty.

 

DynoJet #'s to come today.

 

Awesome. Been seeing your mods on the sig for a while now, and wondering what all the HAHN parts will come out to.

 

1.Mileage (Total miles on car, not MPG's):7500
2.Estimated Mileage since tune (ditto):100
3.List of Modifications (Engine mods only): All hahn catless downpipe, charge piping, intercooler, intake.
4.Type of Tune:Area47 1337 t00n at modified by kc
5.Dyno Results(How much HP and TQ you gained from stock, not just the numbers): stock dynoed 244 whp and same for tq and after tune the these are SAE numbers i got 338 wtq and 309 whp we can easily get way more but im being nice to the stock clutch
6.Problems with Car Since Tune: nothing at all exept need to replace tires soon and NLS isnt really the same
7.Aggressive Driving (Use a scale of 1-10, 10 being you WOT every chance you get, and 1 being your pedal has never reached the floor board): 7
7.Anything else you would care to share: the car pulls so hard i can hardly keep it on the road when i shift but its soo fast it pins me too the seat and i just hang on lol

 

Fred told me ~205, which is really low, he might dyno again when we get the downpipe on, so I'll see what I pull then

 

205?? that dyno hits right in the gut, when was the calibration checked last thats what i wanna know?

 

Shouldn't realllly matter, I know the gains that I got were about the same as everyone else, so if it dyno'd stock ~240 like everyone else, that still puts me at about 300whp on another dyno

 

true i see your point

 

I know you told me about SMG before. Ive been looking into it I was just checking out there page. So you liked their work? Im still planning on waiting to see what GM comes out with, but Id like to get some other possibilities lined up.

 

6000 Mi on car. 1000 Mi since I had it tuned. I have a Dejon SRI now, but with tune only I gained 54 whp 83 wtrq. Havent had it dyno since the intake. I have had zero issues since I had it tuned except my tires seem to be wearing out really fast now No clutch slip issues ever on the dyno or the street. Iam probaly a 4 on the agressive driving scale as I average 30+ MPG since I bought the car. It drives just a docile as stock until you put the hammer down then it is a completely different animal. I have all the torque management removed from my car and frankly 1st and 2nd gear are almost completely useless at WOT. I need better tires It puts a grin on my face to give it just over half throttle in 2nd going 35 mph and having the front tires break loose instantly. A tune is the best $250-$500 you will ever spend on your TC.

 

We have had a cobalt meet there before and people never leave happy. IDK when the calibration was checked but I've stuck with that dyno since I've started and that's the only real way to know what gains you make.

He basically built my custom turbo setup. He does great work almost obsessive. And, all his tunes are strong and have never popped a motor.

Mileage is consistantly in the 31 to 33 MPG range, even at 75 MPH. I almost have to pinch myself about how much fun this car is. Chevy really did a "good one" this time.

Absolutely love this tune amazing numbers out of it and a smooth boost pressure apply based of rpms, helps with wheel spin, also 1st gear has a 7psi limit to help launches

 

I'd recommend Fred and SMG to anyone, he's a real cool guy and loves what he does. He's done quite a bit of work on cobalts and knows his way around a car. He's got a nice little shop in a nice quiet neighborhood, stop in and chat with him.

 

What???

with the tune? and they covered it? you have a lenient dealer and got lucky

 

Where in MA are you from? I know Hopedale is about an hour and a half from me.

 

No way. From Waltham?? It's exit 18 off 495. Map quest puts you there in about 46 minutes.

I have his cell number if your interested. I can get the shop number too if you want.

While I'm at it I might as well say check out fycracing.com for local car enthusiasts meets.

 

1.Mileage: ~6400
2.Estimated Mileage since tune: ~100
3.Mods: Currently stock w/tune
4.TriFecta Tuning
5. stock was 244hp & TQ but no dyno since.
6. 1st gear is useless wile racing, I need to have them bump the boost down to 10-12psi in 1st
7.Aggressive Driving: right now I would have to say 7 but its still new to me and will fall to take advantage of the better mpg's

 

Currently I'm out at school in Westfield (til I graduate in May), but live in Spencer (next to Worcester). Little under an hour drive to SMG from my house.
