I have always wanted to add more horsepower to my car but have not wanted to spend much money and wanted it to be something that I could easily remove if I sell it one day (which probably wont happen). Then I came upon this http://www.autoaccessoriesgarage.com...rformance-Chip I was curious if these actually work. Also I was wondering if they can screw your car up. Does anyone have any answers to these quetions?

 

For some reason the link you posted, send me to "2007 BMW 335i Exhaust System - Borla - Split Rear, Stainless steel" Lol...might want to fix that if it is an error of yours =)

 

That should work now.

 

nope is not fixed

 

now try

 

ok.. yes they do work but it works in conjunction with whatever you have in ur car for example if you have headers a mild cam exhaust u need a performance chip in order to get the most out of your performance parts, one thing alone doesn't add that much hp to ur car, also u need to use 91 octane gas or equivalent in ur state.

 

Do you have to use the high octane gas or will it still work on regular unleaded but not as well. As far as I know my car has no aftermarket parts and I cant afford to use high octane gas.

 

it runs shitty without it, with the ones i've used u need the high octane... at least I have seen a difference when using a lower octane

 

How much horsepower would it add if I used 87 gas. And how much would it add if i used 91 gas. Thanks

 

Do a search , most will say all they do is lighten your wallet.
None of the off the shelf chips do anything for the cost

They work ok for a car with some bolt-on parts, but you have to wonder how much power comes from the octane increase. All they really do is modify the ignition tables which is why you need the extra octane, to ward off detonation from the increased timing.

 

How big of a cost increase is preimium over regular per fill 2 or 3 dollars?

 

Which is why for the $$ you are better off getting a custom mail order tune tailored to your car; not a one size fits all chip

 

HI i got a chip from here for 110 shipped to my house it is told to give you 17 hp and 20 pounds of tork http://tbichips.com/305mods.htm i have to use 93 octane gas i get better mpgs to it seems

 

im only speaking by personal experiences and i did mention they work if you have other performance parts... for example if you install a cold air intake or throttle body spacer and stuff like that to increase the air flow to the engine you also have to use a less restricted exhaust system otherwise you wont really see an increase on performance...

I do agree with you that some chips do do shhh*** specially from ebay lol

 

So it sounds like most of you are saying it is better to save the money up for something else like a cold air intake or some other bolt on parts then.

 

Lol or exhaust - headers back. CAIs are garbage for our car unless you make it yourself. The stock camaro intake tube is one of the least restrictive parts compared to exh manifolds, heads, etc etc. Headers you'll notice a difference in the seat of your pants.

 

lol i agree...

'87IROCZOWNER69 u misunderstood the cold ar intake part i was just using it as an example of parts working together, but yea its hard to get noticeable power increase without putting money and bolt on parts in our cars.

 

So everyone agrees I should save the money for some headers and a full exhaust system then.

 

Yep. Read around these forums and find your ideal header size. When swapping them, you'll immediately notice a difference between these iron exhaust manifolds and whatever header set you buy. The ports, the interior dimensions, the weight.

 

What is a good set of headers to use on a 91 GTA?

 

Hooker 2055s are good, come with a nice ypipe as well. Or Dyno Dons from Top Down Solutions too. Just use the search bar man

 

What would one of you recommend for my 87 IROC 5.7l 350?

 

All headers for thirdgens fit both 305 and 350 engines, 82 to 92. Like someone recommended above, the hooker 2055's are great (one of the best shorty header kits). If you don't mind extra work, you could also go super-comp long tubes (hooker 2210s) which is the direction I'm currently traveling. Use search bar.
