If you're really dead set on getting a new HE take a look at the Gords Ford unit. One of the best out there and fits like a glove. Most HE's mount right where the stocker is and are parallel with the bumper.

Do you plan on drag racing and hot lapping your car a lot? Just curious as to why you want to spend money on a mod which you may never see any benefit from...

as you might knwo if got a 2.76 pulley .its a street car but want to be able to take out some modded ls1s ..rpm outlet will give me an exchange on that sct tuner ,,i dont think they will give me my money back ,,haven hard enogh times getting them to e mail me back,they said what do you want to exchange it for ? so i need to buy something for the price of the tuner ..i just wanted my money back ,,i wish i would have left it stock.
 
Well just so you know there is no performance increase by adding a larger HE. All a larger HE will do is allow your intercooler to cool down quicker when you're not in boost. They are kind of a waste of money for a daily driver.

Why not just go ahead and buy a copy of Windows 2000 or XP for your PC instead?

where i live there lots of traffic ,sitting for long periods of time ..i just want to make sure that im not going to deadinate. even the afco org. series is bigger than the stock one.

Sitting in traffic for long periods of time will not cause detonation. The HE will have NO EFFECT on detonation. It's sole purpose is to allow the intercooler the ability to return to normal operating temperature quicker than normal when not in boost.

yes but if i hammer it right after sitting long time,that could cause detontion. the sct tuner thetll give me 225 bucks back for it.cause it was in a kit form..i dont know if i should keep it or exchange it for the heat exhanger?

Negative. Your ECM will pull back timing automatically if it see's IAT2 temps above a certain level thus preventing detonation from occuring. Your scenario could only occur if you were to run low octane (read non-premium) fuel, or your tune was so f'ked up it's commanding too much timing to begin with.

they burned me a chip, i havent gotting it yet ,waiting for air mass to come in they where out of them ,they said it would be close to pegging 5 volts. so im waiting ,,and stressed out!.i was going to get them to dyno tune it for me after i got the chip ,,without it i couldnt drive it 175 miles to them ,,this way i can drive it to them with the chip there sending me..i talked to people here in town but they cant burn a chip ,another place said bring me your car for a week and we will tune it for you ..they got no dyno ..they drive it they said ..is that b/s ? there a month behind on dyno jms that is ..i hope to have my car tuned right so i wont damage anything...u.m should i keep the sct tuner. then just take the chip out? when i get dynoed.what would be best ,,with the sct tuner they could ,save my stock tune in it ,,and burn me the tuned one right ?:shrug:

I would be very leary of any shop that states you need a new MAF without ever putting it on the dyno and establishing the fact that it truly is pegging at 5v!!! I seriously doubt an unported Eaton with a 2.76 is gonna be pegging the MAF. Even so there are better ways to handle that problem without resorting to a new MAF. Even though you are unable to interface the SCT tuner you have with your home PC what is preventing you from using it on the car? Didn't you buy the tuner as a package deal along with the 2.76 pulley? Didn't they pre-load a custom tune onto the SCT unit before shipping it to you? If so why are you not using it?
