I took the plunge and purchased the full Hahn aftermarket kit for the HHR SS. I'm so tired of all the OEM issues I've been having, of which I don't wish to get into here. Needless to say, I am looking forward to better sound, better power, and most importantly, better quality.

Here is what is coming:

Hahn PPC Tuner
Hahn IC
Hahn Charged Air Piping
Hahn Cat-less Down Pipe
Hahn Cat-back Exhaust

They gave me a great discount for buying it in a bundle. I'm sure there will be those of you out there that may not agree with going with Hahn for whatever reason. But their quality is better than others I've seen such as "Dejon". And the discount they gave me made it competitive enough in my mind to get it. I spent more on wheels and tires than I did on this whole package, so I'm pretty stoked about that. I'll try and get pics if anyone likes.

Nothing wrong with Hahn parts if you want to pay the money.

But as far as the Tuner, you should have gone HPT or Trifecta.

For the same money (or less) for the Hahn tuner you would have gained a heck of alot more power and torque out of all those bolt ons.

 

Yeah, hahn parts seem to be made well, just dont let them do the work... Their handheld tuner is a joke though, hpt and trifecta will put down WAY more power than you could do with anything and their handheld tuner. I dont think that handheld can even support a larger turbo or anything else lol.

 

Dude if you can return the HAHN tuner. **** runs real rich. There has to be a tuner in your area that can tune you for quite a bit less than that canned tune ran you

 

It cant its a POS canned tune

 

congrats on the overpriced parts. i hate to say it but it seems like you haven't seen any other parts out there other than Dejon & Hahn. we could of helped you save A LOT of money if you would of just asked for our advice...... and i'm totally agreeing with what everyone is saying about that tuner thing. it's complete junk. see if you can back out of that purchase atleast.

also be sure you get t-bolt clamps for the intercooler piping or the piping will pop off everytime you go into boost.

places like ZZP & Performance AutoWerks make amazing parts also, just a FYI.

I forgot to mention that I burn money in my spare time as a hobby, lol.

Seriously though, thanks for the tips Rally and BartSS along with everyone else. I don't ever intend on going with anything more than the stock turbo setup. I've got an '86 El Camino SS that needs some serious lovin' in my garage so pumping any more HP out of my daily driver just isn't in the cards until that is taken care of. But, I intend on driving the wheels off my HHR so maybe at some point I will look into a custom tune or at some point down the road learn the art myself considering I plan on having the vehicle for a long time, which means less and less custom tuners will be bothering with the HHR in the next 5-8 years. I used to have a 96 Impala SS and there were aftermarket dealers and tuners everywhere, can't hardly find anyone bothering with them these days.

I don't drive my SS that hard too often, I commute a fair distance every day so I primarily use my power to merge, shrug off would be tailgaters , and deny those who would cut me off in areas that go from two lanes to one. I'll definitely contemplate the advice you have given me on the other reputable performance sites and on sending back my canned tune to Hahn. I know I should have looked for advice on here first, but I didn't. That is life... I got a 700 dollar discount from Hahn so hopefully I didn't get butt rapped too badly. They dropped their prices since relocating to Florida. If you are interested I'll let you know how everything goes. Thanks everyone!



I checked prices for autowerks, obviously as you guys stated, the tuning was a lot cheaper, but exhaust and IC were almost identical in price. I didn't see any piping offered by them for the HHR downpipe or charged air. I didn't even see an HHR area for zzp, they specialize in the LNF 2.0, but not the HHR so I couldn't tell what they offered. I'm sure I could contact them. I don't know what is interchangable between the two models, things like downpipes, exhaust, and intake can be different. You'd know better than I... I'm just saying. For someone not in the "know" zzp would be easy to overlook for an HHR owner. Thus, me missing them.

Bart... you were saying that their tune runs rich. Do you have any numbers on this that anyone has pulled? Are they running above 14 on the ratio? I know on a NA engine the sweet spot is between 12-14 depending on the application.. 12-12.5 is usually what people like to see on carb'd applications for max power and preventing lean conditions. You'd have to catch me up on what Turbo setups generally like to see.

 

Look at the DYNO on HAHN's Page Air/Fuel ratio's are there, But don't quote me on that.

I'm in agreement there hasn't been any additional downloads for PPC in over 3 years, and yup it's canned. It was the first one out though, as a send-over from SAAB. Yes, thats where they got these little motors. Should have been called EURO-TEC instead of ECO-TEC.

There are better tunes... Trifecta over HPT, IMO. Both can be tuned to your parts, and more importantly it can be tuned to your local enviornment.

But I have to ask.... thats a good amount of products.... if you don't mind..... How much was this package deal by comparisom to individual?

Find someone locally who can do the job for you with one or the other tunes.

 

i have informed both AutoWerks & ZZP that the parts they make for Cobalts WILL fit HHRs. they do need to add HHR sections, but you can find the parts under the Cobalt sections for now. downpipes, catbacks, intercoolers are the same. the hot side charge pipe is a tad bit different but they fit just fine, i'm currently running the ZZP hot side charge pipe w/ their silicone couplers and i'll soon be putting on the ZZP cold side so i'll let you know if that works too..... i don't see why not. the only real difference between a Cobalt LNF & HHR LNF is the intake..... i recently had a little experiment with a Dejon SRI for a Cobalt, it wouldn't fit without removing the windshield washer tank (which is something i like having, so it won't be happening).
