I recently found a superchip 3715 micro tuner on ebay and won it for like $40 but its vin locked and i was wondering how well it works on these trucks. I dont wanna pay $100 to get it fixed if it dont help. I just figured if nothing else i got me a $40 code reader.

 

if it was not advertised as VIN locked, then you've been sold an item that was "not as described". you need to contact the seller, and insist on a full refund including shipping. return shipping is your responsibility. if they don't refund your money including shipping, open a "case" against them in ebay. you WILL win, provided you follow the procedure, return the item, and get a TRACKING number on the return shipment.

if you knew it was vin locked, then its your problem, and actually - $140 is a pretty good price. i paid about $230 for my 3815 and I like it. the truck is much more drivable, shifts to TC and OD at better places, and it corrects my speedometer.

 

+1 for what dhvaughan stated. The seller is always considered guilty until proven innocent on eBay/PayPal. If he screwed you over, use that system, its designed to work for you, the buyer.

If he said "vin locked" anywhere in the description... and I am assuming he did if it only went for $40... its worth the extra $100 to get it unlocked. Contact Superchips, they will tell you your options.

 

Not that it matters LOL But I agree that it's worth the 100 bucks to have it unlocked. I also agree with the OP that it's worth it just as a scanner for the 40 bucks. As a scanner it will do multiple other vehicles.

 

I'ld pay the 100 bucks and get it unlocked, I just bought one for 185 bucks and figured that was a good deal. Seems to make a difference in driveability to me.

 

I'm not sure what the difference is between the 3815 and the 3715.. but I [aid $235 for my 3815 and it's worth every penny

 

iwhitne, what do you think is the better mod between the HS 1.7's and the 3815?

 

Is it worth the power increase? No. I didn't notice jack when it came to power increase. It is worth paying the $100 for the diagnostic capablities though. I also like how my tranny doesn't shift into OD until 50mph versus 40mph. It makes climbing hills and merging onto the highway a lot easier.

 

curious did you use the 87 or 93 octane program? I heard the 87 doesnt do anything and you need the 93 to see any real results...

 

thanks guys
