same brand dynos should read very close to each other ... regardless of which country you're in. If it was a dynojet you should be close to dynojet numbers in the US. of course humidity will affect the numbers some but there's been CA cars that have dynoed 300+ whp stock, and CA has heat as well, and the highest octane fuel available is 91.

im willing to bet that putting the car back to stock minus headers will make you the same, if not more power than your current setup.


AMS im not going to get into it with you since you sell these products that supposedly make power. all i know is that i haven't seen any dynos from you that show the gains that you claim your products will give. your crank pulley, headers and software will not make 40+ whp on this motor period. I've seen you advertise that they would but no proof to back it up, no dyno sheets, nothing. The B.S. flag is up and i did see you were called out repeatedly on the "other" forum and again you failed to show any concrete info about the claims you make.

the dyno sheets are on the website, all it takes is opening ones eyes.

Headers alone make 25+HP which is a decent chunk of that, 2nd cats make a good 10HP, and crank pulley makes more as well. Thats not even including software or any of the other stuff. There is plenty of power to be made, its a 5.5L pushing 63HP/L stock.

hi guys! there have beed several cars alread that proved that the dyno reads kinda LO 1st id a JUN/NISMO 1000whp gtr skyline it got 1000whp at australia but onlt 8xxwhp on our dynojet, 2nd an ERICK'S RACING fully built drag 2liter drag honda engine in CA it made 280+whp in philippines it made only 248whp

the heat in our country is far different on CA we got 37C or 99F day temp here far hotter than CA. and also as here is not that good

yah i know peter. i wish i could have even got the same power as yoour car. arrrghhh philippine climate sucks for our cars bigtime

but ill be getting the car today . hope its tuned already.

another example is the HONDA s2000 stock ones reads 205-211whp in US on our dynojet it reads 270-271whp my modded one with intakr, exhaust, ecu etc... only got 192whp. so there really is a big difference on our dynos

AMS Performance

yes, High heat & humidity is not good for power at all. You really need a custom tune for your specific environment. Using the DD dyno will ensure you have the best performing tune once complete

there are dynos posted on this forum that show your headers not to make anywhere near 25whp. in fact it is closer to 10whp. i'm sure your crank pulley makes next to nothing as i havent seen one independent dyno to show any gains, and where is the 10hp from the 2nd cats coming from?didnt you just say that removing the cats removes back pressure and causes a LOSS in power?!?!? any independent data any real world testing? you do know you cant just add up 25+10+crank puley and get 40-50 whp right? cut us a break buddy ... you would be more successful if you kept your claims honest and stopped throwing numbers out of your ***.

that said there have been many experienced engineers here and in other forums that have called BS on your inflated power claims and you have failed to provide any real world data on how you come up with the numbers that you advertise.

im going way OT here and i dont have the time nor the desire to expand on this subject any further as it's already been discussed in great detail and a simple google search for "AMS perfomance mercedes" will clear up any confusion.

yes heat sucks up so much power from our car. but ill be getting the car today the tuner said the tune is finish so ill be picking it up later to try it and let it adapt for 1 wwek then dyno again if still short on TQ im ready for plan B put the stock piping back and just add X pipe and race reso

IMO headers are a waste of money, my Kleemann headers, down pipes and primary cats removed gain nothing but noise. Show no gain on dyno, didn't make 25-30hp like ppl think.
Save your money and the headaces. My Kleemann headers was a waste of money...All my Kleemann mod was a big waste of money. 20K down crapper

Jons95c36amg

Thats why I keep mine stock! NA motors are not like FI which have big gains.

hi guys! just an update i got my car back from the tuner. with the new tune all i can say is wow. car is very responsive felt , TQ is back on low end, a very strong on top end, revs fast, accelarates fast. im gonna let it adapt for 1week then dyno again on november. altho the tuner said he think i have to replace my MAF sensor cause its giving low voltage signals. so im gonna get it check by the dealership and also im still planing on puttiing the stock exhaust pipe back to gain more TQ. im after the TQ on the car

amgalex

How did you tune?
reflash or what?

pinoyk20

custom tune by upsolute

amgalex

so they flash your ecu or do they use a piggyback device?

pinoyk20

they flash it tru the obd port

amgalex

sounds impossible

i thought ecu had to be takign out of the car for a flash

pinoyk20

yup they took out the ecu and wait for the program for 1night cause the tune came from austria. upsolute's main office. then in the morning they returned the ecu to my car the tune took 2days. cause we send the copy of my AFR and dyno graph to austria plus the good thng about it is that they have samples of our fuel and they know what type of climate we have here in philippines so they can adjsut the timing.
