hey on the matter of chips

is it better to buy a chip off a site and give them the list of your mods or actually buy a chip and have it dyno tuned?
and what is a good site to buy chips off of

Re: hey on the matter of chips

It depends on what mods you have, for a stock or nearly stock car, a mail-order tune from a site like vmptuning.com would do very well. However..a dyno tune is always best because it is for your particular car, not just a car like yours with the same mods. I have a SCT xcal2 from vmptuning.com and I love it, no need for my car to be dyno tuned since it is so near stock, not worth the money for me. But, to answer your question, talk to vmptuning.com.

Re: hey on the matter of chips

like low said, for bolt on applications, a mail order is probably the best route. sure a dyno tune would be nice, but the price you pay might muster 5-10 extra ponies.

id get a handheld, you can load their(sct or diablo's) general tune which takes advantage of any boltons you have, and from there you can increase/decrease timing or increase/decrease fuel, depending on how much you are willing to go. i tune alot of cars, so i bumped up timing to full and fuel as lean as possible (The ecu will add fuel in anyways if the o2 reading drops) until you get knock, then add back in some fuel. basically on a bolt on setup, youre going to get your power from Timing advance, so get that as high as possible, then work on fuel.

however, if later on you go with a power adder, the accuracy of mail order tunes become less and less able to make a correct tune when youre running california 91 octane and theyre used to new yorks 93 octane, and the climate are 100% different. alot of parameters need to be taken into account when it comes to tuning power adder setups, and is best left to a dyno tune. good thing is, if you have a SCT/Diablo, most tuners can use those, as they can upload the tune right into the handheld and flash that into your ecu. so while you spend 3-400 for a few ponies with your bolt on setup, its not like its completely useless later on when you get the big boy mods.

Re: hey on the matter of chips

expect 5-7hp from a chip but you obtain other things that help to make it worth while... do not remove the rev limiter though thats just stupid.

Re: hey on the matter of chips

i dont think you can remove it fully, though i pushed mine back to 6500rpm so i can use 4th gear longer during a freeway run so when i came into 5th i wasnt at such a low rpm range. IMO the small displacement modulars can handle those revs, especially with mere bolt-ons and no power adders. as far as taking my cobra that high, no, i usually dont need to, theres no need to break that many laws in one night.
