im looking into getting a hypertech chip but i have ran across alot of skeptical information while doing research, i was wondering if anyone has done dyno or has any personal experiences with chipping their car. im only considering it because i have a chip available to me for about 1/4 the usual cost

 

As long as you are not paying full price for the Hyperjunk chip. I would go ahead and install it if you have a basic stock engine. But note! its NOT going to give you screaming performance. I do use a aftermarket Chip from Fastchip.

 

did you notice anything.. say like in numbers off your 1/4 or gas milage or anything

 

Only difference from the Stock GM 350 chip I used to get up and running, was that it changed the shift point to the better & turned my fans on early until 35 MPH.

 

I know that it added more timing, because after the chip install, I was no longer able to run midgrade gas. Premium only. Being able to go to a 160 stat was a big help; the 'bird always ran better at lower temps. I never took the car to the track before the chip/K&N/Flowmaster changes, but after it did run a best of 15 flat. Local track is at 4,100 ft, so about a 14.3 corrected.

This is on an 89 Formula 350 twin cat. BTW, chip was a gift. Wasn't planning on installing one, as the 'bird is my daily driver. K&N was cause I'm too cheap to buy filters every 3 months (dusty out here), factory muffler made no performance noises, so it had to go.

 

You can achieve the same results as a hypertech chip by advancing your timing a couple degrees and running premium fuel.

 

I put in the second level Hypertech chip and I did notice a slight increase in "seat of the pants" performance. This was after installing headers and cat-back plus cold air. Was it worth the full price I paid - no, but a 1/4 of the price and it is so easy to do - why not?

 

i'm so sick of chips.....hypertech and jet are worthless for their price. even my tpis chip isn't the greatest.


onto DFI!

 

IMHO changing your chip isn't worth it unlees you're custom tuning it for the specific car. If you can get a HyperTrash for next to nothing then go with it, just to turn the fans on earlier. But don't expect any real gains.
