Hey guys.

I recently inherited a 1997 1500 4x4 Suburban with the 5.7L engine.

I have been a VW guy for quite some time and wanted to see how the mods align/differ between the Turbo tinys and the Big brute.

OK, ina VW, mods usually go like this :Chip, xhaust, suspension, intake, bigger turbo.

my question is, in a Suburban, will the air intake/exhuast free up the fuel mileage like it does in the small car? My MPG went from 30-35 when I swapped out to a less restrictive exhuast in the GTI. If I could get 3-4 MPG out of the Suburban, that would be awesome.

Have you guys seen any improved mileage from aftermarket parts, or does it just give more power?

Also, while I am here.... What should I change immediately on a truck with 100K and dubious maintenance? Fuel Filter, Trans fluid, etc...?

my question to you would be what is youe vehicle plan sheet look like? do not have one? make one. there is too many different ways to go and each will help a diffferent task. are you going to show? tow? cruse? or mall drive? just like your "Bug" you do not just toss money and expect good to happen. you need a build or plan sheet...........mike

Good point. Sorry, I left my mind reader turned off.....

My goal is to just have a daily drive that gets good mileagelol and is durable. My experience has been that letting it breathe easier lets in more power and mileage, but that may just be a turbo-specific issue. Basically, I won't make any performance mods that will sacrifice fuel effeciency, but usually with a (again VW) chip your mileage goes up a bit in just commuter traffic, the mileage sink is when you find those extra ponies living at the high altitude area in the tach.

I know the 350 is THE generic V8 with more parts options than you could ever imagine, and I like that about it, because it would make it cheaper to fix/upgrade in theory.

Another question, is a 97 OBD1 or OBD2? I have a VAG-COM for OBD2, and I think I can use it on GM cars as well if itsa OBD2.

Thanks for the quick replies.

Thanks for the responses guys. At least I know my OBDII port will work, now to comandeer some GM software:great:

So Michael, are you saying the chip isnt worth it? I should just do boltons.

If I swap exhaust, I won't want it much louder than stock, what do you guys recommend?
