what kind of power gains is typical for getting an LT-1 PCM tuned at like PCMforless. I have jet hot long tubes, hooker cat back, 58 mm. throttle body and an underdrive pulley.

 

With only adding a MadZ28 tune to my setup (CAI, cutout, catback, !CAT) I went from 263HP/302TQ to 281/312.

 

Wow,
I just put mine in last night. I hope my results are similar
Next up - headers

Must reach 300RWHP ... then set new goal

 

I usually tell people anywhere between 12 and 22rwhp. Dallor per HP its one of the best things you can do.

 

 

Very much agree.

 

what kind of gains do you think i can achieve from mods in my sig? it sucks not having the $$$ and time to get a tune yet, but soon..

I think you'll gain alot considering the the mods you have.

 

Maybe it's just me, but when I got my pcmforless tune I lost around 5hp. and 8 lbs. of tq. sent it back in it was running too rich, got it back running too lean and pinging. so I sold it, just running stock tune for now, until heads and cam goes in then getting dynotune.Of course I could not get a datalog of it when I ordered the pcmforless tune, hard to do when I work 3rd. shift. anyway, for me it will be better to get a dynotune than playing mail tag trying to get it right..
