has anyone have had bad expereinces with this programmer? or heard of any problems it may cause? i think it messed up my comp!!!

 

I got shitty gas mileage on my car. It was installed when I bought the car. Previous owner gave me the hpp with the car.

The car also had a one bad cat.

I uninstalled the HPP, replaced the granatelli maf (which is shitty too) with the stock one, and installed LTs/ory.

I gained 100 miles per tank. LOL

 

I have the HPP3 I think my computer loses the program after about an hour... it runs better and pulls harder right after the tune but an hour later its back to normal...

 

From what ive heard with the Caprice/Impala people they are junk.
Better off going with a real tune.

 

I first bought one a few months after I got my car mainly to get rid of the speed limiter and increase shift firmness. It worked great for those, but as far as the power tuning goes, you need to get a real tune.

The HPP isn't worth the money.

 

I agree, I had a buddy go down the same road, so he sold the P.O.S hypercrap cause it did almost nothing over remove the speed limiter, correct the speedo, and lighten his pocket by $400.00

 

Luckily I bought mine on eBay for $250 back in the day and sold it a few months later for $225. The $25 was well worth breaking the 150 MPH barrier.

 

My car runs ALOT better with it but it just doesn't seem to last for some reason...
