Well...I suppose we could make an educated guess based on the
other tens of thousands of LS1's with his mods.

320-325 rwhp is a good guess. But it's a good idea to get the dyno tune when you can afford it. Not so much for the dyno number but rather for the tune itself. My car was running very lean and the tune fixed me up and gained me another 29 rwhp.

But I was an extreme case with major A/F ratio issues. Most bolt-on cars will gain 5-15 rwhp from tuning. Still worth it though IMO.

We all asked the same question one time or another. Listen to Darren, I did, and I gained 15hp and 20 pounds of torque. I hate it when he's right.

My wife says I'm never right. BTW I know a 7 year old that says he can kick your butt at pool John

i hit 318/326 (on a fubar dyno???) with an 01 z28 with mods in my sig. keep in mind that you have the ls1 intake manifold, not the ls6, and you have LTs rather than MTs, oh and you ahve no cats (damn you).
