apten chip vs jet chip - dyno chart

93 Mark VIII

Registered User
While out at carlise, I had the chance to put my files in an 89 Super coupe that already had a jet chip. The base pull with the Jet chip made 207RWHP, and the air fuel was decent. I would imaging it would have made a few less HP without the jet chip.

anyways, after putting in my files, and we ended up with 226RWHP. I didn't have to do anything significant with my base file, but it took two pulls to get some data on a gauge problem he was having. So 3 runs later when we did pull #4 the intake temps were up 20 degrees. Just wanted to pass that along for those considering a jet chip :D

Which one is better

So which chip do you feel is the better one. I was considering the Apten chip...Along with a set of thier HP heads:D

Thanks,

my air/fuel was a little richer than the Jet chip, which means it wasn't really in the a/f ratio at all. Most of the power was made in timing and removing torque reduction.

which would I go with.... haha!
