+ intake + tune/tuner puts you well over a grand total

 

Are we gonna add in the cost of gas to drive it and the oil because you put miles on it? Adding anything in for wearing the tires down? Or brakes to stop it, or the clutch disc?

The boss manifold is a "next step" kinda mod, if you're not the kinda mustang owner who already has a tune, and CAI, then the high rpm nature of the boss manifold is almost certainly not for you.

 

I totally agree !!

 

Don't forget the cost of air for the tires no I'm in no way complaining about the costs. All I said was I'm sure if I drove one I'd be $1K poorer. If I want to go faster in the meantime I'll hop on the bike and rev it to 16K

 

Getting back to the original purpose of the thread ...

I took everything apart and re-assembled. Was able to replace the 2 sheared bolts and was very careful about the fitment issues with the B302 throttle angle vs. the Steeda CAI. Tried the carb cleaner spray and I really have no vacuum leaks. BUT, alas, still the issue with the fluctuating up/down idle (550 - 750) + the occasional stall out on idle.

With the manifold out I did notice some brown coloration on the intake ports (which I think is indicative of running with too much fuel). I tried the set up with both the 87 Performance and the 87 Street tunes from Bama ... no difference. One odd thing is that I have a hard time restarting after getting gas (odd), but, once I get it going, it's fine.

Bama continues to be super helpful and I am sending them another data log tonight. Any ideas, guys? (Oh, and I bought a set of fuel injector o-rings (18) but turns out I didn't need them b/c ever one of the single green o's were still on the injectors.).

Thoughts?

 

i'd replace the o-rings anyway maybe one is nicked or torn. as i said before, that is the exact issue that my buddy had and it was a vacuum leak. the brown you saw in the intake is likely oil blow-by, these cars are notorious for that and it doesnt take long to get noticeable oil in the intake. i didn't read all of this, but did you spray the TB cleaner around the outter edges of the intake? if you do and the idle clears up when you spray in one spot you know that is your issue area. it might be worth it to take the car to a shop with one of those smoke machine testers that can pinpoint leaks.

 

Can it just be your tune? I have a few tunes and a couple have idle issues that can not be resolved but 2 of mine the car idles and runs better than stock.

 

Well it was the tune! I hooked the fuel vapor purge line back up with the sensor and got a new tune from Gus at Steeda and all is well !!! Can't thank Gus & Steeda enough for jumping in and volunteering to help me !!!!! I am happily motoring again

 

Not all tunes are created equal.

 

Thanks for letting us help and thanks for using our product!

 

I ran a tenth slower with a Boss intake and Steeda tune over stock intake and Bama tune.

Bama tune for the Boss intake was awful down low, tons of lost torque, I probably should have ran it too but I'm confident it would have been even worse.

DA when I ran with the stock intake was 2700, DA when I ran with the Boss intake last friday was 500, so the losses were actually worse.

More than likely going back to stock, unless I want to spend more money on a dyno tune...

 

Talk to Shaun at AED before you go back to stock and see what he says. The guy is a tuning master and will give you the truth if you can get it all sorted out or not.

 

Thanks man I will give him a call.

 

I'm having the exact same issues but don't know where I could have a vacuum leak? How far did you torque the bolts down? Did you snap any?

 

Hey I have the same issue and VMP whom did my tune doesn’t think it’s them. What did you do to solve it op?

I'll second that!

 

I’ve definitely noticed a increase in probably 30 or so hp power and maybe 15 fp/t, but i was pro-tuned prior to putting it on. Though i have a gain my idle seems off and my car is running hot after a drive with my fan kicking on I believe. Possibly just low on coolant because i had a issue i thought i fixed but wonder if the intake could be causing it now.
