First off 96s were not chipped. They're PCM driven OBD 2 cars, programmed with a laptop or some such. The ONLY LT1s that were chipped were '93 speed density cars, after that they went to PCM driven MAF. Your friend probably got the hand held tuner from hypertech or something similar.
A good tune will make 10-15 RWHP on an otherwise stock car, with a nice increase over the whole curve, OBD1 or OBD2. And that's mail-order, a dynotune (although not a good deal for the money without at least a cam) could make more.
The tunes those hand held devices have are crap. He could see 10 rwhp at best at the peak. Once he starts modding the tune could actually cost him power. He needs a real tune from madz28.com or pcmforless.com. If he went from running 87 to 91 octane as well as tuning it, there will be a big difference. These cars stock NEED 91 octane (10.5:1 CR and aluminum heads). It even says so in the owners manual and on the fuel door. That's probably where his biggest difference came from. My car (stock or modded) runs like total **** on 87.
