2008 GT Vert: UDP, DR NA-NSR Cams, Airaid CAI, CMDP, BBK shorties, HI-FLOW cats, axle backs, and Alum DS. Just normal run of the mill bolt-ons.
So i've been tuned by AM for a while, but since i bought and installed the Detroit Rocker Cams i thought i'd try Brenspeed for a new tune to compare companies since is hear mixed feelings on AM. Well decidedly to one side and not very mixed really!
Not Bashing AM just thought i'd try something new and since it's Brenspeed's cams they might know more about them as far as tuning goes.
The issue is now i'm getting a lot of bucking in 1st and some in 2nd. I mean violent bucking. Whiplash territory actually. i'm not even in the clutch when it starts. i'll have been out of the clutch for 7-900 rpm's before it starts always in the 3-4k range is where it starts.
Straight line drag race driving is fine and really light 'baby' driving is fine, but if during normal driving i don't shift at 2900+ RPM into 1st or 2nd i need to get a neck brace.
i asked them about it and was told to clean the TB. Admittedly i just installed the TB with this tune. The TB was spotless though so it isn't in need of a cleaning. They offered to pull out half the throttle response and said the amount they add "wasn't for everyone". i took that to kinda mean i'm a shitty driver and i need to learn how to drive my car.
Unfortunately I don't have an AM tune with the TB to compare with yet, but it is ordered and i never had the bucking with AM tunes. I'm not sure why i didn't order it before, but well i just didn't. Once i get it i can say if this is a TB issue or not.
TB is FRPP 62mm by the way and it seems to function fine. (I know i get no real benefit now from this, but it fits into future plans. Plans rhym with "flurbo")
So should i go back to manual driving school or is it a tune issue with way to much throttle response? My laptop died a few weeks ago so i can't datalog right now to see what they are commanding in the tune.
The Brenspeed tune is for sure the faster tune between the two without question, but i actually do believe the CAM's sound better with AM tune. More loppy idle.
i can't afford the chiropractor bills with the Brenspeed tune and i'm afraid if they pull out half the TR i'll be exactly where i started with an AM tune.
So is this a Driver Mod issue or a Tune needing Revision? Will 1/2 the TR being removed affect the faster tune in straight line acceleration? The TR just changes the points the throttle blades are open for a given pedal position. But Hammered is 100% either way so it should have the same response hammered with 1/2 the TR right?
