After what seemed like forever i finally got my car running good after the HCI swap. i took it to a dyno shop and had a superchip burned for the new setup. the trick flow kit says 350hp and 370tq. i came out with 261.9rwhp and 301.2rwtq. this was with a pretty big exhaust leak. is it just me or is that very dissapointing? i was hoping for 300rwhp.

That does seem very low, as I plan on getting mine dynoed soon also. Having virtually the same mods, I was hoping for 300rwhp anyway. What was your a/f ratio, what was timing set at?

yeah is that the first run or something? timing is right and air to fuel? something doesn't seem right. and exhaust leak would't compensate for that much loss.... give us more info.

What kind of dyno??

If it was a mustang dyno, you're right about where you should be. If a dynojet, something is amiss with youre setup.

dang.... something is wrong. I would have expected 300RWHP. Maybe something is wrong with the chip. Does the car feel a whole lot faster?

I would want to get the condition of the short block checked with a leak down test. Then pull the codes and see if anything is screwy there. Finally I have heard that a BBK can seriously screw with a PRO-M..may want to consider return to stock air box...just some thoughts. You have all the parts for 300HP but the weakest link is holding you back, you just have to find it.

I would look at everything and check to see if you have any vacuum leaks or small things like that.

If that doesn't work then take out the "PHAT" stereo system, maybe thats the problem

I would say it is the superchip or block. Yank the superchip and try again?

First thing that I don't like is the fact you have an exhaust leak & yet they "burned" a chip anyways? What happens when you fix the exhaust leak? Running fat as a skunk at low rpm would be my guess. Did they tell you to fix the leak & then go back for a "final tune"? Something is definetly not right if indeed it was run on a Dyno Jet......

P.S. On a dyno Jet two weeks ago my engine made 310rwhp & 301rwtq. Details listed in my signature. The numbers were with fuel adjustments only, no chip, & first time at the dyno just like you. I figure with some experimentation regarding the timing I might find a few more pony's....

yeah, I think it is the chip or something small like that..... how much does a dyno run and tune cost? I want to do one but I have to drive 2 hours to get to one.

The ONLY reason I keep asking what kind of dyno is for the simple fact that a dynojet will read higher than a mustang dyno A mustang dyno loads the drum more than a dynojet. Food for thought, I sold my ENTIRE 302 combo to a member of the corral. Through my tremec the motor made 303/332 at the wheels on 2 different dynojets. Through his lower parasitic loss t-5, he made like 270rwhp on a mustang dyno.
Sorry for the rant, point being, if you were on a mustang dyno you are NOT far off from where you should be. If you made those #'s on a dynojet, then there is a issue. Good luck.

The dyno near me charges $140 for the first hour. He also told me that if I had it dynoed, he strongly recommends that I also get a chip burned, which is another $400. I have heard it is definitely worth it to have your car tuned, but $540 is alot to come up with to "get the bugs out". I know, I know, I know, there is more to it that "getting the bugs out", I'm just jealous because I can't afford to tune right now .

I am not sure what kind of dyno it is. here is the website: http://www.dynolabs.net/index.html . there was a turbo corvette on when i went so its not just stangs. before he put in the chip he dynoed it and it made 254.5rwhp and 286.7rwtq, so i dont think its the chip. i had a smoke test ran on it before the dyno and there are no vacuum leaks. they are gonna fix the exhaust leak next month when i get some suspension done then i will probably get it re-tuned. but i doubt the exhaust leak can account for 40rwhp lost.

Wow....I would be thinking myself on that one.....I recently had a SC burned on a blown Factory Five Cobra with a 302....they pulled 80 HP out from the base run....So the chips work...
I would tend to think its the dyno type??....Your pulling the same RWHP/TQ as me with a Thumper/Tmoss set-up on a Dynojet....No way...That thing would be running sick, and if so and you'd feel that for sure....Even at 5 pulls the dyno guys should have done the timing/AFR...thats standard tune stuff....

Look at the pictures in the website dyno section - it's a dynojet style and not a Mustang dyno.
