Should I be Worried? Dyno Vids Inside Hey guys. I had a my 98 trans am, 80k miles, full exhaust, high flow cats, and lid car dyno tuned late this summer. I recently bought the car basically stock with lid and catback. I installed tsp longtubes, custom y with high flow magnaflow cats, air and egr delete, motor mounts and plugs and wires during the summer. I had my tuner install a 160 stat and while they were installing, they let me know that the previous owner mixed dex cool and green coolant and they also found stop leak in there. They couldnt visually see a leak but they were playing with the coolant pressure tester for an hour or so. They bottoned everything up and told me my car was all fixed up and ready for the dyno. Car drives great and nothing funny goes on with the temp gauge but the more I watch the dyno vids, the more Im starting to question small puffs of smoke my car produces at the higher rpms

Oh ok well you might be fine. A flush would definitely guarantee all the filth and garbage is out of it but if its working fine then run it till it doesn't lol. Just keep in mind you may have to replace the radiator eventually if it had some stop leak in it.

I dont know the reason behind it but most cars Ive seen do this at the high rpm just before limiter or after letting off the throttle for a brief second.Seems quite normal,I sure its more related to the fueling or afr uptop.But if there was something wrong with the tune at that point,your tuner wouldve spotted it on the dyno fairly easily.Doesnt hurt to ask him also if your worried.A good tuner will always want to make sure your car is at its best while making power and suggest anything they see wrong to get you in the right direction.
