i got dyno tuned yesterday... im running is s2 headers and s2 cat back, injen sri, and flash pro... but the numbers he gave me afterward for my torque were a lil disappointing and sounded really off compared to other people ive talked to... torque lbft: before 111.4 after 123.8... hp: before 189.0 after 202.2... i mean the gains itself were good from before but i havent heard of even a stock si that low of torque... im curious if anyone else is running that low or if those are normal numbers... let me know ur dyno numbers too

thunderdome

seems a little low to me as well ... check out all these dyno #'s

Every dyno is different. What correction factors were you running? Some read low, and some read high.

thunderdome

this is very true ... forgot about this

what type of dyno. My numbers are in my sig and thats with without flashpro and tune so.
I think it was just a bad reading on the dyno cuz thats too low to be a correction factor I think Ken. But then again I could be wrong, wont be the last time lol.

hottunedcars

well i think it depends on the dyno too.If it`s an older one and not maintained properly it might show incorrect readings

Don't our cars have 139 ft/lb stock? If so then I would expect the torque t be about 120 at the wheels on a dyno jet.

Greg how were you pulling more torque at the wheels than our cars make a the flywheel untuned?

Greg had an I/H/E prior to getting a tune.

It was a dynopack... I'm going to check out another dyno and see if I read different

I thought dynopacks read even higher because they bolt right to the hub and you don't get the loss through the tires slipping.

Still have not gotton a full tune yet. I did sdjustments myself.

[Quote from AJP]Yes thats true. There isnt a load on the tranny/motor of the car on a dyna pak. My dyno was with I/H/E and on roller dyno. I think it was dyno jet.

if this is the same guy who posted on 8th, you did it on a dynapack right?
something is wrong. because r18's are making the same tq as you with bolt-ons. here's my dyno chart after my tune. you should be somewhere around what my numbers are.
