Wester's Programming Group Purchase!

02-09-2004, 01:11 PM
We're going to be running a group purchase for the Wester's computer programming. 10 or more orders will be needed for a 20% savings. I'll be posting some more info for this in the next day or two. We just need to gear up for a heavy volume of programming orders :)

Here is some info to help you decide what will be best for your truck -

Wester's Performance tunes are now available with these basic choices.

1) 85 octane high altitude tune

2) Dual 87-91 Octane tune (will automatically adjusts for octane)

3) Dual 89-93 Octane tune (will automatically adjusts for octane)
(These dual octane tunes are recommended for all dual purpose (work/play) trucks.

4) 91 Octane HOT tune (much more aggressive than the Dual octane tune)
(Recommended for performance trucks where higher than 91 octane fuel isnít available, like California.)

5) 93 Octane HOT tune (much more aggressive than the Dual octane tune) (Recommended for performance trucks. No, or very limited, heavy towing or hauling!)

Custom tunes to your specific requirements and desires.

The new 87/91 and 89/93 dual fuel tunes will be able to run with 87 or 89 octane in MOST conditions with good performance, or with 89, 91 or 93 when even more performance is wanted. The dual octane tunes are capable of tuning for a higher octane. The factory tune will only advance the timing to the limits set in the original spark tables. Changing between 87 or 89 octane and 91 or 93 is automatic, the tuning will adjust itself for the octane you are using by referencing another spark table.

Under MOST conditions, all the tunes will run fine with the octane programmed for, but altitude, towing, load, condition of the engine, temperature, poor fuel quality, oxygenated fuels, or sensor variations may require choosing a higher octane. Just be aware that under certain conditions a higher octane fuel may be required, and that more performance and sometimes better fuel mileage is available just by using higher octane.

Standard with all performance tunes

Complete reflash of the PCM to your VIN, with all factory updates.
Dyno developed performance tune optimized for your exact engine and transmission combination.
Raised and optimized shift points
Firm, but not harsh shifts
Elimination of all torque management that can be safely removed

Some of the more common modifications to ask for.
Raising the top speed limiter to any speed you specify
Specifying the exact shift points you want in every gear
Firmer (or softer) shifts.

Specific tuning for your modifications, like larger than stock tires, gear ratio change, aftermarket MAF sensor, supercharger, headers, cam change, engine modifications, etc.

The Guarantee

30 day free trial, you donít like it, weíll either modify it, or send it back and owe nothing!

Lifetime warranty (no cost or fees)

Lifetime updates for all future mods ($45 shipping and handling fee)

Lifetime full price paid credit toward your next custom tune for your next vehicle ($45 shipping and handling fee).

This will also be listed in the Group Purchase section of our website.

Here is some of the fine print to go along with the GP -

IMPORTANT INFO: Most products to fill each GP are ordered at the end of the GP. They usually take 1-2 weeks to ship from here, but some items could take longer based on the size of the group purchase and availability with the manufacturer. Depending on the product and our available stock, some orders will be shipped from here shortly after the GP comes to a close. Remember, you need to place your order if you are interested in taking part in a GP. Be sure to check the status of the GP that you are part of on it's closing date to see if is going through.

MORE IMPORTANT INFO: All credit cards are processed a few days before the GP closes to insure everything will go through without a problem and to lock in the order. Orders canceled after your GP order has been processed will be subject to a 10% processing fee. Orders for products that are non-stock items (not normally kept in stock) can not be canceled so be sure that you would like to be part of the GP before you place your order.

WHEN SHOULD YOU PLACE YOUR ORDER?: We find that alot of people wait for the required number of orders to be placed before they get in on the GP. If everyone does this the GP minimum is never met. If you would definitely like to join one of the group purchases that are listed it will be best to place your order as soon as possible. Your credit card won't be charged until just before the GP comes to a close (as long as there are enough orders) and the minimum will be met much sooner. This will allow you and the other participants to take advantage of the savings.

PCM cores - You will need to send your factory PCM into Wester's after you install the new computer. We will do a "core authorization" on your card to cover this computer until it is returned. The authorization won't be an actual charge, but it will hold the money for us in case the core isn't returned. The core amounts are -

Most computers up to 2002 - $175.
2003 - $350.
2004 - $450.

This authorization will be voided after your core is returned.

Orders can be placed online or by calling 1-877-4-TBYRNE.

Another big benefit of this tuning is you don't have to worry about vehicle downtime if you need to do an upgrade. Wester's will send you the new programming and then you would send the old one back.

We've now up to 10 orders so this GP will be going through! Orders can be placed through next Friday (2/20).

It looks like we have some H2 guys getting in on this. There are 35 orders in as of today with 3 days left.

Some customers have been reporting horsepower gains in the 28-50hp range with the 6.0 motor. The numbers on the high side were from H2 and SS owners. The spread comes from how aggressive the tuning is along with other modifications that are done to the vehicle. Fine tuning for other mods will sometimes make more of a difference than just running those with the stock programming.
