All that BS about not needing a chip is pure and utter crap. The stock a/f was a mess- 14:1 down low to 10.5:1 up top. Baseline (001) was with only the mods (Bassani cat pipe & cat back, UPR CAI, 2.93" pulley); runs 2-3 were with the chip- the "street" tune. Runs 4-6 are with the 2.80 pulley (which by itself only added 3hp and 8 ft/lbs) and some additional tweaking/ timing- the "race" tune, 458h/482t. Stock numbers were 389h/377t.
We both thought there was more left, maybe another 5-10 hp & ft/lbs, but he wanted to play it safe and I can live with the numbers, considering the safe tune (~11.3:1 a/f- it looks like a landing strip, almost perfectly flat from 2500 to redline). The chip is a dual-program Autologic unit, but i agree with everyone else- it's the tune/tuner not the chip. I decided to go with a well-known local guy with extensive tuning experience over a shelf chip, so the tune would exactly reflect my car.
Big gains down low. At 2500 rpm:
Stock- 340 ft/lbs.
Mods/chip- 455 ft/lbs.
Not bad for $2,500 in bolt-on's (all #'s SAE)
