those sound like really good numbers for a street gas 2.4. 12:1 pistons ?

im sure you could use a legit tune on a dyno, some bigger cams. that header will work out good for your once you figure out the choke.

keep it up teal !

(SC) header install completed
the only issue so far is how close the #3 "squiggly tube" is to the upper radiator hose. like 1" close. some header wrap should do well in that spot. John did a very good job on the overall "fit". the 3" 2 bolt flange is right @ the corner of the oil pan within 1/4". there is no way that it will contact, however. and the two o2 sensor bungs are properly placed in the collector.
took the beast for a short, on-ramp type, test drive.
my butt dyno did not detect a huge power gain. 2nd gear still breaks traction @~ 5.5k to 6k. only took her to 7k in 3rd gear.
Dyno Tomorrow @ 1100AM

she didn't blow up
first let me preface the changes from the last dyno in july......

back then i was running way too much ign timing.
N1's were @ +2/-3. now +4/-4
ASP budget header.
i picked a comparo run from last time showing i think 235whp. this one is 233.xx/180.xx with more low rpm hp/tq. i was having trouble updating the map. i'd make changes, then save it, but it wouldn't upload to the ecu. in fact the laptop had to be force shut down, then rebooted. and it still wouldn't update. pissed me off! we did change the cam switch points though, and with great sucess. we got rid of a HUGE dip in mid range power by raising the points ~500 rpm.
all in all, i'd have to say the little ASP Budget header did pretty well.
on the way to the dyno, i was monitoring my afr's and noticed it getting richer and richer. to the point of 10.8 to 1 in steady cruising! i was like wtf! it's never done this before. i attributed it to running so cold. the coolant temp was 172* and figured the cts was telling the ecu to richen things up...weird

i'm @ work right now so i don't have access to the chart. i'll post it the 1st chance i get.
