weird numbers
weird numbers i dynoed my car 2 days ago and its and automatic. its a 99 trans am with jus cut out and lid. well they ran from 3rd though 4th for 2 runs.
well my numbers were 347 hp and 430 tq or around that (lost my dyno sheet last night.) i was like omg its a freak. when i got the print out what happened was the shift from 3rd to 4th drops then peaks to thoughs numbers. over all it look like i was around 310 everywhere else. its this normal? what happened there?
also when i got back in my car after they dynoed they my brake light n abs light was on i turned the car off then back on n just the abs light was on. now its been 2 days n still on. i heard the dyno will do that but will turn back off. what can i do to get it off now?

first the dyno operator doesnt know what he is doing. you need to keep the car locked into 3rd gear only for the dyno. second that 400 rwtq is a torque spike (thats why it falls). it isnt a real measure of the power the motor is making. 310 hp is about right and actually a strong ls1 auto. 4h gear dynoing shows less power than actual. you need to dyno in your 1/1 gear (3rd).

I had the samething happen to me with the ABS after my dyno. Mine is a manual tranny but, check back there and see if it got unplugged somehow. It isnt a complicated answer and might not be it, but after i got mine dynoed for some reason the ABS got unplugged. Probably just an odity for me, but you should atleast look. it will be right behind the muffler, there will be a few plugs there. Check them all to make sure there in all the way and secure. If its not that then sorry, i cant really help you.
