Re: performance chips good or bad?
if you had a never vehicle (electronically controlled) a chip can produce up to 15hp and 15lb ft of torque. Older vehicles, you'll be lucky to see 5hp/5tq and fuel mileage gain will not be noticeable. Your best bet is to get a larger throttle body, cold air intake and a freer flowing exhaust to gain maximum performance from your I6. I wouldn't chip it. if you want to, stay away from JET chips, as they offer the least amount of HP gains out of all other brands, and when all told, are NOT worth the money. You'll want to sell it after you buy it.
