Hey guys I just added detroit rocker cams, off road H pipe and flowmasters. Plus i have 410's with cai and 93 tune from brenspeed. My question is when i mash the peddle my car is hesitant but gains quickly. It does not spin the tires until it gets going. I have 255 45 18 on with summer tires. Any of u with similar set up have that issue. Im going to call chandler at brenspeed and see what they got me for my tune or maybe i need take it up there for some pulls on the dyno to get a better tune. thanks guys

do you have a manual or auto. i had the same issue after i installed all the bolt ons, exhaust, etc after i tuned it though it doesn't hesitate anymore. also mines an manual

its an automatic so hopefully i can get it worked out. with the 410's alone i could roast my stock tires not my tires that i have now though. IF i were at the drag strip i would bring the rpms up with brake compressed to about 2000rpms so maybe it has something to do with that. I'll see i guess when i get to the track

what size wheels do you have now did they help with your launch compared to the stocks

Did you have Brenspeed rewrite your tune for the 4.10 gear? They need to adjust shift points since you have an automatic.

I assumed since they had did the install of my 410's that they would know that and write the tune for it. Plus i drove my car 385 miles and only got 17 miles per gallon hand calcaulated it twice. I think im gonna call them tomorrow and see whats up. Just dont seem right to me

You have 4.10s and a CAM and you think 17MPG is bad? I average that w/ out a CAM.
