I would like to make sure that I am clear to my fellow Crossfire members
I did not get a "custom tune" mine was the SI "Box tune" with just a few more dyno tweeks to correct the rich A/F ratio. If I had known I was not running lean with the 185mm pulley - I would have mailed my ECU to LET for the tune and saved a ton of $$ that I spent spinning on the Dyno.
Live and Learn - That's why I share the info - so you - my friends - can save and get the best bang for your $$
Like I said - pony up $75 and I will be glad to go to a local Dyno-Jet (not sure where there is a dyno-Pack in my area) - but unless you think my engine is junk - I don't see how you could feel the larger pulley would reduce your hp??
My only engine mods are:
Resonator removed (yea I used stainless material & proud of it)
MB SL55 Intake - (2 hour install)
LET 185mm Pulley (1 hour Install)
SI Tune
That's it!
** EDIT **
My engine has only 6,700 miles
Si Custom tune was hundreds more then what I paid - that's why I settled for what I did.
