About 1000 miles on my LSA conversion, drivability questions - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

So after install I have decent miles on and have noticed a few things that I cant tell if they are normal (this is my first Camaro)...

I get what I would believe is belt slip at certain points under load, im sure there is some other pulley out there to help with belt wrap.

The main concerns are 2 fold:
first if I drive normal and under 3k rpms the car will load up and sputter requiring some WOT pulls to clean it out - normal?

On the freeway at cruising speeds of 75-85 I am barely touching the gas peddle, its as almost as if the blower is just pushing the car that fast - normal?

Tune issue for sure. Get your belt slip fixed if you have any, and get your tune fixed.

Agree, ck the tune. Belt slip can happen if you have a 2.5 pulley. Did you get the griptech version from ADM?

What pulley setup do you have? I'd ck and verify the belt is correct length too. If you purchased the kit from ADM, it should be.

I can say, very little pedal is needed, I barely touch mine and the car really move ..

I am with the others... fix the belt slip. ADM did my tuning... He dyno tuned it then, spent a couple of hours fixing the drivability.
I can say that my GPI SS1 cam would surge at stop lights (before the LSA)
the driveability is now much improved with the LSA and the CAM.

The only issue is if you do a rolling stop while the engine is still dropping RPM's then decided that you want to go ahead and go... It is very minor and not noticable to the passenger.

To fix your problem I would guess you need a street tune, or someone who has done a ton of FI tunes.

I did my LSA install back in May and I run into the "loading up" condition every now and then. I haven't been able to replicate it regularly and it doesn't happen often, but I know what you're talking about. I do believe it is tune related.

Did you make sure and pin the crank?

JSalt · 09-22-2016, 05:14 PM

Thanks for all the answers guys, unfortunately the shop has been refusing to pick up the phone (we had some issues at first with scheduling that led to un-happiness) so Im kinda stuck until either I physically go in and ask them to fix it since they seem to be avoiding me.

100% correct belt for the pulley and the crank was pinnned
