does LT's/true duals =tune?
 

my car is running like crap at WOT ever since the LT's/TD's setup it seems to be cutting out around 5K-6K rpm. i pulled a plug thinking i might of been running a little lean but it seems to be ok.. do i need to have it tuned?

yes. long tubes will make the car run rich. a tune will fix that and also net you some more power and take full advantage of the set-up

with your mods I would def get a tune just seeing that you have the slp maf and headersd and t-duals get that a/f straightened out and like allready mentioned it will help you get the full power from your mods

I got my car dynoed and had a near perfect a/f ratio with the stock tune.. :)

How hard is it to tune the car yourself with a lap-top based tuner with just LT's? I was thinking about buying a program for myself to tune and play with as opposed to getting the car tuned by a pro since all I have is LT's. I know I don't have the knowledge to tune with a cam, but can I learn enough to tune with just the simple mods I have?

How long have you been running it? If you just put the LT's in, it will probably start working better after you drive it for a bit.

The cutting out sounds like damaged plugs. Did you change them? Did you leave them in while putting the headers in?


Green - You can do it yourself, but you'll also need to get a wideband to see any kind of improvement. I have HPTuners and have been learning little by little. It's pretty tough to figure out, but it's not overly complicated. There's plenty of stock + headers tunes available in the HP tuners repository you could look at.

Yeah, take one and modify it. I did lots of logging when i tweaked existing mods with EFI Live on my Z. You can always benefit from a tune regardless of mods. Stock cars pick up power and torque too.

Does a tune bring you MPG back to what it was stock ? (on an otherwise 100% stock setup)

Please be honest.

i only have about 30 miles or so since the LT's/TD's..car has been parked since. car drives and sounds fine when driving "normal" i did pull the stock plugs out during the install.. 22K on them have since replaced them with TR55's gap to .50 still same results .. is this just my luck or is this common?
guess i"ll call G-Force this week to schedule a dyno tune..
