so i did a dyno run tonight and made 205hp and 183TQ the guy show me the graph and there are alot of zig zag in it he says spark plugs but there farily new any ideas thank

 

You are virtually stock, Those numbers seems fine.

as far as the "zig zag" the ss.sc runs a little rich from factory. But for argument sake, what spark plugs are you running?

 

Aren't you on gm stage 2???

 

OEM plugs from the dealer should i get somethign diff to solve this problem

 

I think zig zags represent clutch slip

 

Clutch slip would actually cause a loop.

 

loops represent clutch slip

 

DEZZIE41 - The first question is have you been tuned. The second question is what is all done to the car and what maintenance have you kept up on?

 

not stage 2 yet...CAI and exhaust i do all the reg oil change and just did the plugs 2 months ago im wondering if there not gaped right

 

on my bros dyno the wheels not really gripping the rollers cause zigzags

 

Post up the graph.

 

His numbers sounnd on the money for HP and maybe 10 short on TQ for stock setup. Maybe pull and clean the plugs and run some lucas injector cleaner though it and you should be good to go.

 

Uhm idk....Ive never seen a stock ss dyno less than 200 BONE stock. So with your 2 mods u might be about 5 hp off and deff a good amount of torque off.

 

Does these zig zags look kinda like these?



Thats like 5 pulls on one sheet but you can see how they are. It was becase their spark sensor wasnt getting a good signal from the plugs. I am guessing yours had the same problem. If its that you have nothing to worry about.

 

mine looked just like that they said change the plugs and try gapping them....just wondering what is the stock oem plugs suppose to be gapped at

 

Please do some research on Dyno's and factors that can cause variations between them...

 

It was just they rpm sensor not getting a good signal. They were probably just making it sound like it wasn't their fault because they didnt want to do it again. haha. Oh well changing plugs is never a bad thing to do. Good luck you got any future plans on modding? Might as well pick up some 1 step colder plugs.
