was just talking to a buddy about this. i said the tune i got...cost $375 (came with the tuner) and gave me 15 rwhp......over twice what i got from the cat back i bought for $400..... and while i'm at it......worst..??? whatcha think...????
my mods at the time were. pulleys catback k&n filter with silencer removed when looking at the dyno sheet i got 230 at the wheels, after the tune. 248..so its actually more.. since then a cai, and royal purple... the guy that does the tunes is very good, he has done a lot for other people on here. it was also with 89 octane
i used to have the diablotuner, i maxed out spark and ran 93 octane, i definately gained some top end but i lost some low down torque I just sold the tuner and now i can definately feel more low end torque and a loss of top end. It seems like its a lot easier to screech second after taking the tune off
Best bang for over all would be nitrous. Not sure if that is what you meant. $800-$1000 for 150hp. Worst bang for buck would be a plenum or cai. I don't think i saw any gains with either. At least no seat of pants gain.
I quit doing the bang for the buck thing... its all about the end goal when you're talking bolt ons... Nitrous and F/I will forever be debated as to which is the cheapest for the gains in the long run etc... The two mods I feel the best about (ie instant gratification) 1. Pro-Chamber (Felt it, Heard it, love it!) 2. Plenum / TB combo (Felt it... not power but response, Heard it once again smoothness, love it... except when I gotta polish it before shows)
wait wait.... So, that thing that they advertise on Spike, which seems like a hoax, actually works, or are you being sarcastic... Tell me more!! Does it improve MPG like they say? I got the stickers, 2/$1 100hp and the chicks LOVE IT
LOL, thats hilarious. Thanks! I just got my Steeda pullys in the mail today. If they're as good as I'm hearing I'll be back on this thread!
