Plugs aren't going to do anything for you. I've got one step colder plugs and got zilch.

 

Interesting I might have to look into that.

 

so since the TS dyno i've got the new plugs and the iso-thermal upgrade to help w/heat... hope it helps HP. considering JWT S2 cams and w/new tune... gotta learn to live w/the HP gain to dollar ratio 1st.

 

I wouldnt expect it to make any noticeable difference but who knows it might get you a couple of horsepower for little money spent.

 

I cant wait to see what 410+wtq feels like with the 100 shot installed.

 

yeah, i didn't mean gains from stock to the cold one's... my stockies where bad and i was only firing on 5 cylinders most of the time. not so much a power adder, more like a power fixer.

 

Jeremy was telling me earlier that when I get the UTEC not to expect more than a 10whp gain after we tune it... He says the NA revup motors are hard to squeeze anymore power out of when tuning.. I have seen other people pick up 15+whp with a tune, is that just because they are on a different dyno?

 

i picked up 18whp and a much smoother TQ curve from my Technosquare reflash and dyno tune BUT i'm non-rev-up.

 

What mods do you have? Nvm looked at your cardomain.. in that fly-by video you bounce off the limiter for a little, but you have an auto..??

 

mod list is on the link in my sig... check it out and lemme know what ya think.

 

What did you dyno?

 

AS007, you have similar mods to me. Check out this thread about my tune:

You might get more, or less. It depends on how well your stock ecu has adjusted. Generally, the more you pick up with bolt-ons, the better the stock ecu has adjusted, thus the less likely you are to see large gains from a tune. However, if you added all those mods and only picked up say 5hp, then you could expect more from a tune.

 

247whp/240wtq w/a heat soaked engine on 5 cylinders and bad plugs...

 

too bad i don't have a 6 speed... ahh, it's cool SoCal traffic sucks even worse w/a stick.

 

Your making some nice power there! And thats a nice 1/4 mile time, what was your 60ft. time?
