I own an ’89 535ia and until recently have been pleased with the power
it produces. Well I had been hearing all this talk about engine chips and
how much they improve power and torque, so I figure I should at least
look into what’s available out there. I came across the E.A.T. chip and
noticed that it seemed to be priced less than most others… Then i noticed
that people were raving about the benefits they were experiencing with
this chip. Not expecting too much, I decided to go ahead and order the
chip from https://prestofamily.com

Mark is a great guy to deal with and
made the whole experience that much better.
Anyway, the chip arrived sooner than promised and I put it in that very day.
It only took my 20 mins, and I am not by any means a mechanic. I started
the car and let it run for a minute or two to get the car used to the chip.
I took the car for a spin and wow… I almost had to get out of the car and
make sure I was still driving the same car I have been for years. This little
chip is amazing… Hands down the best investment I have made since I
bought the car. To anyone looking for a great performance gain in all aspects
get this chip. I had a better idle, better gas mileage, smoother pull through the
revs and much better response. I am still amazed every time I get in the car.
GO GET THIS CHIP!
