just dynoed with mods in sig put down 268rwhp and 275rwtq and i swapped to 28lb injectors and they were at 92percent duty cycle at 5300 rpms wtf is up the guy said it was because my injectors were too small and i baught the car with the stall so when i drive it it flashes at 3200-3500 so i think its that size but he said he thinks its much bigger so he tols me to swap injectors and come back for the rest of he tune and he said he thinks ill make 315 this is on a mustang dyno but damn thats low

heres the graph he gave me i didint look at it till i left i was too dissapointed it just has hp and torque im gunna call and ask tomorrow about the afr

 

What is your AFR at? Plugs good?

 

the graph he gave me just shows hp and torque numers at 3500 rpms to 5300 where he stopped and the plugs are new

 

Well you would have continued to build power past 5300 I would assume. Knowing your AFR would help a lot. It was probably off a decent amount.

 

When i was cam only i put dow 390whp locked with that cam through a fuddle 3600....somthing is really wrong there

 

he didint finish tuning it cause my 28lb injectors were at 92% at 5300 so im going to swap the injectors and go back but i still think thats low

 

It should definitely be run to at least 6100... Something is definitely off though. Check the plugs/wires/fuel filter/clean MAF/ Make sure air filter is clean. Get the AF ratio numbers to us.

 

yea i had the car sit for 8 months with it not moving so im gunna change the fuel filter and clean the maf

 

the only thing i dont understand it my injectors are maxed out at 268 hp i thought they were easily good for 400

 

So, you had the 28# injectors in while it dynoed? If so you're injectors should be fine. I would say: 1. Did you install the cam yourself? If so did you line up the dots on the timing set? 2. What springs are you using? 3. Check for cracked plugs or a bad coil pack. 4. Dyno graph, A/F ratio, and more in depth info would help lots. The tuner should be able to help alot considering he's the one monitoring everything going on. I'm surprised he doesn't have any thoughts as to what might be wrong.

 

yes it has 28lb injectors i installed the cam myself i lined it up dot to dot and i have crane dual valve springs he said cause my injectors were too small and my stall is too big i dont know the exact size but it flashes at around 3200-3500 when driving so i assume its that size but he said its gotta be much bigger he expects 315 after i have bigger injectors

 

I just don't see how your injectors are maxed out. The mods/numbers in my sig are on stock injectors that ARE maxed out. That was on a dynojet but last time I checked there isn't a 30% difference in the two.

 

heres the graph he gave me i didint look at it till i left i was too dissapointed it just has hp and torque im gunna call and ask tomorrow about the afr

 

me either i dont think they should be maxed out either

 

Christ something isn't right there. The graph almost bends over backwards. That is beyond Mt. Everest. Unless you have a 4800RPM stall lol...

 

when i drive normal it flashes at around 3200-3500 but when i punch it it jumps up to like 5300-5500 and holds that rpm untill the mph catch up

 

I ran that cam "cam only" (+ supporting bolt ons) on my 99 C5 with stock injectors (26 lb) and they were only at like 72%... Who is doing the tuning for you?

 

kaltech in deer park new york seemed like a good known guy

 

315? Wow, he should have a whole lot higher expectations with your setup. I would get a second opinion from another knowledgeable tuner.

 

Somethings wrong i did 400rwhp on an unlocked vig 3800stall on motor cam only on stock 241 castings... 236/242 601 610 112 lsa cam and 540rwhp unlocked sprayin a 125
