To me 7 rwhp for $350 just isn't worth it. That's why I said it's "my opinion".
I can think of many other things I would spend $350 on before using it for a chip.
I'm not saying chips aren't worth the money on other cars, but to me an N/A bolt on only car isn't going to gain that much from the chip. I guess if you look into how much the speedcal and the sims are, it's a little cheaper, but I still wouldn't spend $175 on 7 rwhp.
I don't even run sims on my car, I'll just leave the CE light on until it burns out.
