ATR Chip Decipher

[SCOOBY DOO]

Guys, I have a gent with an ATR chip in his car. It's being replaced with a TT chip. Numbers on it are HP 137TX and then 328C written with a pen. Pitbull 1989. If anyone has any info on this chip I'd be appreciative.

Pitbull chip was pretty aggressive back in the day.
High timing.
Keep the boost low especially without octane.

I had that Chip in my Car when I first bought it.I knew nothing about these Cars back then and Pete Hoffman told me get rid of it Immediately and get Eric Chip.I didn’t listen to him fast enough and took out the Motor with it.Back in 2008.

Between ATR and Kenne Bell, they helped bolster head gasket sales for decades.

And the guy that invented the engine hoist also invented the v sicks.
Seems he wasn't selling enough hoists.

Until the early 90s (When I started doing chips), the conventional thinking on chips was timing, timing and more timing. Very few people messed around with the fuel curve and just used stock.

I brought the low timing/high boost thing to Buicks and it just kind of took off from there so Id avoid any of the early chips no matter who made it.
