Anyone else chime in on this? I did just install the uicp, licp and intake so it is possible. Would a leak cause said symptoms?

 

I'm suprised the tuner didn't say anything. The torque going down like that does look like doo doo.

 

Where do i need to connect to check the whole system for leaks?

 

I usually do it from the intake pipe in place of the maf.



Build one of these. Fairly simple.

 

Yeah I have one made. Do you have to use tank air or will a bike pump etc work?

 

Air tank for sure since you need to build up a decent amount of pressure and look for leaks.

 

not bad power at all with posible leak. Id like to know the correction factor though. This looks like a tune with cams on a IX. congrat should run 11's.

 

congrats

 

Nice numbers. Btw, do you have cams?

 

man that tq falls off bad. power band could use a little smoothing but decent numbers!

 

i think they say like 15% correction factor for a mustang dyno?

 

time for springs, retainers and cams. the power will hold up top with these mods

 

So thanks to all that suggested I check for leaks. I checked before I went but when I checked again this morning I found a split vacuum line on the passenger side running into a solenoid. So I fixed that then found that my tb seals are leaking so I guess I will have to order new ones or get a new tb with them in it. Anyone ever had to change those seals? And how hard is it?

 

It's not too bad. Here's a write up on how to do it.

Don't want to come off as being mean, but 349hp 329tq, @25psi is pretty dang high for Intake, Pipes, and exhaust with a HFC. Got a feeling their CF was bumped up a little. Thought you would be running e70/85 for those numbers.
