    tbi chips

    I think I will email the guy and ask him some questions about those chips. Anybody had any bad experiences with aftermarket chips?

    Thanks

    I emailed the guy a couple times and this is what i got back:

    Typical gain is 15-20hp for a mere $30 investment. I offer a satisfaction guaranteed or full refund.
    I do manufacture these chips and have specialized in TBI systems for the past few years. The chips really don't wear out. If you buy a new computer for your truck, you must reuse your old prom. The only way they die is due to physical or electrical damage. You can either run high octane and stock 195* thermostat or reg gas and 160-180* thermostat. Gas mileage pretty much stays the same unless you keep your foot in it all the time. Yes there have been returns for one reason or another. I have sold a few hundred chips and have had less than a dozen returns.

    What do you guys think?

    Anybody have any thoughts, suggestions, info about chips period? Would this be a worthwhile upgrade on my daily-driver stock K5?

    Thanks

    Well, he's telling you it doesn't affect gas mileage, but I'm sure it will. What those custom burned chips do is 1) tell the computer to dump in more fuel and 2) advance the timing about 4 degrees (hence the higher octane comment - to prevent detonation). So, if you're not worried about spending more money on gas, more often - than I say go for it. /forums/images/graemlins/smirk.gif

    Well, lets see.

    Say you go with the chip, and it requires more octane. Say 91 to be safe, and you can easily run on 87 now.

    Thats *only* $6 PER fill up with a 30 gallon tank. (figure $.20 more/gallon from 87 to 91 in most cases) That adds up quick for "only" a $30 investment. Of course, if mileage goes up to compensate, great, but I REALLY doubt that you'll see a $.20/gallon increase in mileage.

    Sounds to me like its mainly timing advance. If you have to emissions test, you may be running the ragged edge of passing with a chip like that.
