I know it's hard to tell without a dyno, but I'm just wondering from the parts that I have right now on my mod list in my signature what I might be running at, and what parts would be really smart to go with next.

howarmat

mayebe 275-285.....without a tune you are really falling short. a TUNE is like gold with the cars

mygt500

Don't you have to have a tune after install with the LT's?

howarmat

no you can get by without one. The car will run, not optimally and might throw a CEL. Sometimes not though.....with the kooks being a mid length header, the CEL might not be triggered

06Redfire3V

+1 to howarmat.

Thanks Matt.....did not know that

Nuke

+1 with Howarmat's estimate. We dyno, stock, around 265 RWHP. With your mods you may be picking up roughly:

• 5 from the CAI
• 1-2 from the TB
• 0 from the mufflers
• 5-10 from the headers
• 1-3 from the X

These numbers may vary depending on the dyno, your latitude and longitude, religious beliefs and annual income.

lol thanks guys...what's a CEL?

acascianelli

+0hp from the TB spacer...

CEL = Check Engine Light.

You need to get a tune, you're being held back severely buy the stock tune. You should be able to hit 300whp or close to with that setup plus a tune.

i had similar mods:
K&N CAI, BBK LT's and o/r x pipe, boomtubes, and canned tune
#'s were 291 rwhp/ 302 tq.
i would say next, go for cams and tune
