Question about 98 LS1s

Can anyone tell me why the Diablo programmers are only for 99-02 and not the 98? Thanks.

98's have a different ecm... The pin punches are even different. I use to use the hyportech programmer for just 98's... Now the HP Tuners will work on all years including the 98's !!!

Exactly. Supposedly the 99+ are easier to tune, too.

I have a Hypertech Power Programmer for a '98 for sale. PM me if you're interested.

Thanks for the gouge guys! I've heard HPPs don't do a whole lot for M6 cars so I'll hold out a bit for one of the others.

Hey John, mail order tuning is $125 and can do much more than a handheld. Your location is convenient, you can ship cheap UPS ground and it's over night between us. More info here and a link to a contact form if you have any questions: http://www.lsxtune.com/shop/product_...roducts_id/631
