Wow! This thread kind of reminds me of that old Western movie staring Clint Eastwood "The Good, The Bad and The Ugly" of tuning
I couldn't reisist, anyway I have some more "Ugly" to add for the newbies to consider before opting for a tune. Here is the scenario, please humor me for a moment: Let's say you add a few mods like headers and a CAI. Your Camaro will need a tune for the headers (otherwise it will display a check engine light). So you have the car tuned and all is well. Now the 2010 Camaro is likely to have a few if not several TSBs announced in the future due to areas of the PCM and car that need tweaks. You take the Camaro in for a routine oil change and guess what??? The GM Goodwrech folks reflash your PCM with the GM recommended/required changes. Whoops, so much for your performance tune.....it's wiped out. If you are heavily modded you are going to be driving out of the dealer in limp mode or calling a flat bed or at the least have the check engine light display. So note to self, talk to your tuners ahead of time and ask if they will reflash your tune if GM needs to perform a PCM update. Also be upfront with your service advisor you can have he/she write "DO NOT FLASH PCM" on the service order but ask what updates, in regard to TSBs, are out there for you to consider(this is what I did when I took the Vette in). This way you can plan for the time when your car will be down instead of a surprise WTF Happy Tuning P.S. Please just take this information for what it is, my experience and the experience of others I know. Let's not speculate why GM does this we all have a rough idea why (liability, consumer satisfaction, stock holders, its the right thing for most consumers etc) Just know that this can and will happen to some in the future so prepare for it then it will not be a big deal to fix. I hope this has been helpful. Last edited by SSRider; 06-29-2009 at 10:59 AM. |

So you are somehow not maintaining the air/fuel ratio? If you let more air in and out you also MUST let in more fuel. Now if you are saying the engine has to do less work to intake or exhaust, then ok. But if you bring in more air you have to bring in more fuel with it.

But seriously; good discussion here. I'm actually learning some things amongst the bickering. As to the OP; I really feel no lack of power in my maro' ... probably cause I'm used to driving a base Cavalier. But compared to my parents Grand Prix and CTS; it has waaay more kick.

You claim you can make and engine more fuel efficient, more powerful and more reliable than GM? Sorry, but that isn't something you can pull in the aftermarket. You grossly underestimate the millions of dollars and thousands upon thousanads of man hours GM spends to make and engine as economical as powerful and reliable as possible. And you think a "tune" improves ALL of those? Sorry, I work with too many people at GM and I know how hard they work to do this. Can't let that simply pass.

Well wether it be a tune from the dealer. Or something else is the matter with my car, Something is wrong. I won't go aftermarket tune. I'll have my dealer figure out the problem. Car has power but my 60 times are about 1.5 seconds slow from the advertised times. My SS is sbarely getting the LT times. I'm not a pro driver but it's an Automatic tranny and I should get 5.0 seconds by just punching it in the right mode. Maybe 5.2 even, but not over 6.

Also as number 3 states you can't just put more oxygen in the engine without increasing the amount of fuel to maintain the correct mixture...unless i'm missing something here as well. Not trying to stir anything up but your statements go against things i have been taught. If you can point me to some literature perhaps that i can read it would be appreciated. Thanks in adavance.

If you open the intake to take in more air," yes indeed you increase fuel to maintain the A/F ratio"
While also opening up the exhaust there is less friction, less heat and less acceleration needed to obtain the OE level of performance. Less engine speed (to achieve the same as stock). Now like I said, if you put your foot in it your going to lose your fuel economy. Obviously. But if you use your CAGS (shift eliminator) and find the,"sweet spot" you'll undoubtedly improve fuel economy. I did it in my 05 silverado. Do you really think I'm dishing derogatory slander against GM employee's? What I'm saying is real word shit. Facts. The almighty dollar. Totally off topic but cold reality of how FU things can be in this real world. Do you think our troops were incapable of winning the vietnam war? Compliments of the US government. Now do you think there are reasons why a perfect car has never been developed? The capability is there without a doubt. Next. |

ok so i read it normal for cars with lower miles to feel slow? (i got my car a few days ago and only have 200 miles on it, a Auto 1SS). If so, how much actual power difference do you feel when you finish the break in? And even though im not supposed to , i have kind of been friving with a heavy foot. will this hurt performence in the future?. thanx
