Now now. Don't be so hard on the guy.

While 15 hp does seem bloated, you will get some improvement. 5-8 hp would be reasonable expectation, 10hp beeing the max I would expect. That is if the new code plays nice with the 17# injectors. Timing bumps have always increased power, if you can manage to avoid detonation. With the lower compression ration on stock SEs, detonation will not be a problem with 92 octane gas. Plus the speed limiter will vanish and the rpm limit will be higher. Its a good deal for the price.
