PERFORMANCE CHIP

[Cruuzin LV]

I just got an SCT programmer on Saturday and flashed my L99 on Sunday. Night and day difference. Gas milage seems to be about the same "When I keep my foot out of it" Another added bonus for the auto trans I noticed is that when you let off the car doesnt drop to 4cyl mode and slow down. You actually coast and dont have to get back on the throttle. The shifting feels drasticly different and almost too firm but I'm slowly getting used to it. For me it was well worth the money. I did a K&N Drop in filter and the Programmer and I'm very happy so far. Now I'm saving for LT's and a CAI.

Hmmm, what I find weird about all this chip talk is the ad I found at the end of this thread:

I have made a number of ill informed stupid posts in the past have gotten similar smart ass replies. And I will most likely write more. But one should not take all of this too seriously and you have to be able to laugh at yourself. I think smart ass replies are fine as long as they are actually funny.

A handheld programmer is if you want to be able to change basic things. Some company's include them in a package deal also with there tune pre-loaded. These tunes typically only account for the parts you just bought and assume the rest of the engine is stock. There usually a very conservative tune also to avoid engine damage. Some good tuners are using a handheld tuner with great success, but there having you download a custom tune to the handheld device then loading it into your car. It's called remote tuning and it will work great with a competent tuner creating the tune for you and making adjustments to it from the data logging you might do.

You are correct in that a dyno tune is typically done on more advanced parts combinations or radical engines. A Dyno tune can also be done on a stock engine if that's what you want.

You can tune either way, but you must have a competent tuner or it's a waste of time and money.

Looks like their chip (box) splices into IAT wiring, so technically you could say there are chips for these car's, but not what I would call a tune.
