This auction is for a TOWMASTER MEMCAL for the 94-95 TBI 454 trucks. I will need the 4 letter prom code from the white label on the silver computer box behind your glove box and pretty much any modification info for your truck so I can make sure you get a compatible chip that will work for you.

Rev,shift points on auto trans, torque converter lockup and speed limiters are altered for for better towing. I will also want to know the gear ratio for the rearend as well as the tire size for best towing performance. NOTE: Rev limiter should only be altered if you have changed the cam and valve springs on your motor. I have a few of my favorite cams listed on the www.tbichips.com website.

My chips usually get either the same gas mileage or a slight improvement with a typical 10% HP and TORQUE increase.

NO HASSLE REFUND: If the chip does not perform the way I claim in your vehicle, I will either offer to make you a new chip or refund your money in full including shipping charges.

Any questions or if you wish to use a credit card to pay for your auction while avoiding  your credit card info being passed on the internet. Give me a call 336-471-2827.  I do not put credit card info on any computer system for security reasons.

NO PERSONAL CHECKS. Buyer pays $6 US or $10 International shipping. Also, International buyers especially should consider the optional insurance for their item. Please remember to include shipping charges with your payment. I will ship the chip anywhere in the world.
