so I have a 2.8" pulley, 60's, 1-step colder plugs, Injen CAI, Megan Racing Catback, and i just recently put on a zzp header/dp (w/o cat). Before the header/dp i was tuned and dyno'ed 235 on a mustang dyno, some said my numbers were a little bit low? Im getting retuned on saturday, anyone have any idea how much of a power increase i should see?

seems low, who tuned you? and whered you dyno?

that does seem low, ive seen guys w just stg2 put down higher numbers than that. should be around 250ish. ditch that megan exhaust.

Whats wrong with the megan exhaust?? Changing to another 2.5" aftermarket exhaust wouldn't help his situation at all. He just needs a good tune.

get rid of the injen and megan(and the zzp header downpipe if they aren't 3") and get a 3" intake, and a full 3" exhaust. then if you can afford it, methanol injection. then profit.

my mods are in my sig and i dynoed 246hp & 209tq but it was on a dyno jet

meh my stock TC dynod 228whp and 219lbft ... that's low compared to most tc's too... it depends on the dyno... don't take them to heart too much every dyno is different. besides weather, temperature, humidity, bad gas etc. changes things.

tREBs

go to a track and get some real numbers please...
Dyno's should only be used as a tuning tool.

I have, i ran a 14.1 @ 100 mph

i was tuned by Tune Time Performance, dyno'ed there too

well your numbers and times line up. i dyno'd 231/205 stock and the best i could do was 14.2x with 2.0 60's. so there wasn't anything left. something is wrong with your tune. or just a bad combo of parts hahaha

MSHETZ

there is 2 tuners local that are better, red05ss/sc or byt turbo... there is a dyno in aston,pa right off of 95, thats where we went, tillman performance if i recall. pm them..

sounds liek dawg shizzle nizzle...

the zzp combo is awesome. 3" exhaust is too big for his mods. if the op plans on goin with a more aggressive set up later he will benifit from 3" but for now i would stick with a 2.5 if i were him. as for a larger intake... it really dosnt make that much of a diff in my opinion. but in theory he would benifit from a larger intake seeing how he has dropped pulley sizes.

or your dyno reads high, or his reads low. I don't get how at this point in the game, people still don't understand that different dyno's read differently.

okay then. why did i dyno 273/250 with 3" intake, 3" header, 3" downpipe, 3" catback, 2.8, 60s, 90/10 meth/water @10gph....same dyno...

when he dynos 235 and runs low low 14s. and i dyno 231 and run low low 14s. i'm pretty sure the dyno adds up to the times... i was running all kidns of 14s that day. but i had about ten 14.2x runs. so i'ld say it wasn't going to go any lower.

i may have had a "factory freak" but once you start modding it all gets relatively evened out

i was tuned at tune time aswell and i dynoed 270whp 235wtq mods in sig

hockeylx92

you have a few more mods than me, doesnt seem like it should be a 35whp different tho, i think i have a **** tune. im getting retuned tomorrow so we'll see how that goes.

damien

iTrader: (3)

**** tune, correct. That's all I have to say though.

hockeylx92

just got the retune today....245whp on a mustang dyno...still ****

you got low TQ numbers

gwatson650

mustang dynos factor in a lot more things in their readings. not surprising that your numbers are low

EXsoccer1921

iTrader: (14)

you also have no cooling mods. i remember my numbers weren't too impressive at all when i just had the 2.8 and 60s

damien

iTrader: (3)

I did 255 on same dyno same weather tuned by the same guy. 2.8/60's no cooling mods.

hockeylx92

thats weird

BlueSS/SC

I have the same setup, minus the cat back, and i ran 14.1 and dyno'd at 240hp on a mustang dyno, and i was running 10's in afr...pig rich lol

Dyno readings are over rated sometimes, imo
