I'm fairly conservative in these matters, so I'll probably opt for the PPK (sans stickers, obviously). But, I will certainly be missing the extra hp/tq of the Dinan tune.
Anyone here have experience (good or bad) with Dinan tunes in the GTA (I think Budd's is the only authorized Dinan dealer)?
Is it possible to purchase an extended warranty on the car if the car has been Dinan-tuned?
Please see the attachment in my post above(post #14). It will answer the last question for you..
