tst programmer and dashboard Guage cluster
 

Does anyone know weather or not a tst powermax 3 programmer for a 1998.5 3500 24v should always have the boost or fuel light on mine doesn't show either when it was first on it did. Also when I hit a hard bump or take a right turn to sudden or sharp all guages in my truck will sieze and then completely stop working then once iv hit another bump they will reset and start to work again any information or pointers for this problem would be greatly appreciated

Sir:

I would thoroughly check all the ground connections first. If that doesn't help, you may need to give Mark Chapple a call @ TST to see if he can get you another unit out.

John_p thank you I have started to clean the grounds on everything and I have contacted tat they said to have the performance shop re look at it to make sure none of the connections cam loose with the programmer. But I'm still not sure y my abs light comes on and gauges stop working after a hard bump and then start to work again after another bump

Boost is always on. there is a cycle that happens when you first start the truck should flash a few 8's this is normal. I believe if there are some errors on communication with the TST there would be differant flashes.
