[QUOTE="Jam421, post: 16329124, member: 110985"] When Lund tuned my car for a KB Mono Blade the first couple of pulls were 2500-4500rpm just to test for wrench lights & driveability. Each successive pull / datalog brought up rpms. Then come the WOT stabs to redline. All told we did 6-7 pulls. With the mod my motor pulled real good up top but mid-range up 3000-5500 it felt a bit flat compared to my old Twin Blade TB. A custom tune shop did a tune eval where we found AFR was mid-10's low 11's. Custom shop past dyno pulls had AFR in mid 11's-12.2/ I requested Lund bring AFR to those parameters & signed a waiver for Lund's 93 Octane Race Tune. After that tweak my power curves were UP everywhere from 2800-6500rpm. Just Awesome. [/QUOTE]
