issues with 228/232 110+1 cam
issues with 228/232 110+1 cam So I just had the cam installed and tuned. Drivability is horrible. Bucks under 1500 rpm and torque doesn't come on untill 3grand. Torque peaks at 360, which is crappy IMO. Power is good at 387 but again, doesn't really come on untill 3grand. This was proffesionaly installed and tuned on a mustang.
Cam card says 228.8/233.2 .592/.598 LSA is 109.8 and ICL is 108.8. Cam was installed with an ls2 timing chain. Could this be a problem? What do you all think the problem could be. I'm pretty sure the problems down low are a tuning problem, but I don't understand why the torque numbers are so low.
I'm really disapointed with the way this turned out. I spent a ton of time researching and spent a lot of money on this thing and it's so annoying to drive around town.

My car bucks a lot under 1500 as well, but I have a much larger cam. I would take it back until it's tuned better. The torque should not be peaking that early unless you have some really restrictive heads/intake.
Your tq should peak much later. When I had stock 317's on mine with my ls6 and ported tb, my tq was peaking around 4700. But, then again, I have a much bigger cam so that accounts for some of it.

I have a 228/232 on a 112+2, with ported heads. It bucks and surges only very little under 1500, and that's when I don't give it any gas. Yes, torque hits more around the 3k mark, but that's expected with a bigger cam. Mustang dyno's are stingy and more accurate, a dyno-jet reads a good 20-30hp on the high side for cam/ head&cam cars, so take the numbers with a grain of salt. Maybe your tuner is running it real rich and isn't adding enough timing down low. I also have an M6 so it's easier to drive a big cam. Are you A4? If so, what convertor are you running?

I would have to agree here. sounds like tune is off and if A4 you might need a higher stall and/or gears . M6 should not buck at all. I'm running 231/237 112+4 on M6 stock rear gears, only bucks slightly below 1500 rpm's when not pressing on the gas pedal.....

It is your tuning that sucks.
387/360 on a mustang dyno is good numbers
Look at the difference between your trq and HP only 27
That means your trq is plenty. With bucking issues you can only blame the tune.

I'm running the same cam but on a 110+2. Took quite a long time to get it to where it doesn't buck at no/low throttle. Timing, fuel, throttle follower/cracker, IAC, RAF, etc. all have to be worked on.
Like others have already said, seem like your making pretty good power. Just need to work on the part throttle tuning now.

But with the tune woek i got, it was more managable. I need a gear, i am still on my stock 3.42. My buddy has a 242/242 LSK lobes on a 4.10 gear he has no bucking and the same guy tuned it.
Good Luck, i hope my info helped some what
EDIT: my numbers are in my sig with waht i made with this cam

If it was just tuned on the dyno for wot runs, it also needs to be tuned for drivability.
It seems this cam requires a bit of time to tune right, I've read other people complain about the same issues. But I'm still thinking about trying one myself soon.

that is correct. this cam is very picky. I had to go back to the shop about 4 times for more worl to get done.
IT IS ALL IN THE TUNE WITH THIS CAM!!
Thanks for the responses guys. This forum is always great!
But anyway, the torgue peaks later than 3000rpm (I'd tell you exactly where if I were at home), it's just that at that point is when the torque surges and you can see it on the plot. Hp does the same thing.
I'm very happy with the hp number, I just thought the torque would be higher. Maybe withing ten or so of the hp number.
I'm working on getting in touch with a very reputable shop up in Philly to straighten things out. I'll let yall know how it turns out.
And if it matters the car has qtp lt's and full custom duals with no cats. M6 with stock gears and ls6/ptb on the intake side.
