Custom Chip 90 91 92 TPI 5.0 5 Speed
Must have 90, 91 or 92 5.0 TPI 5 Speed.
What you get...
1. Memory Chip Adapter where custom chips plugs in then into ECM ($35)
2. Brian Harris Stage 2 Chip ($144)
3. TPI Parts Custom Chip ($60)

1. The adapter needed to use these chips...
2. Brian Harris Stage 2 chip. This requires a 160 degree thermostat, and at least 91 octane fuel... more details below... My car did have headers and a few of the "free mods", taken into account...
http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEWAX%3AIT
3. A "stock" chip with a few changes...
The "few changes" that both chips have....
VATS disabled. I was going to use them with a remote start alarm.
RPM and MPH limiters Disabled....
This cost over $200 new....
$75 shipped within US....
I'm getting an EBL P4 Flash, reason why I'm selling them....

Re: Custom Chip 90 91 92 TPI 5.0 5 Speed
Just wondering if this will work on a 88 tpi 5 speed trans am ??? and is this something you have to solder in or does it just plug right in... I have cash in hand and need something new for upgrades....

Nope.... 88 uses MAF TPI, this is for a MAP TPI, the 90, 91 and 92 years...

Stock 305 heads, cam, etc... I have Hooker 2055 headers and K&N air filter...
Note the 305 5 Speed cars had the same cam as the 350 TPI did the 90 to 92 years.

Palric, these chips are for a 5.0, not a 5.7.
