Tuning question/opinion
I'll be taking my car to IPS Motorsports on Friday for a catback swap and for them to do a few other smalls things. I also told them that the car runs rich and I would like them to possible touch up the tune. They quoted me $450 for the dyno tuning. My questions are: 1. Is this worth the cost of possibly no gains and maybe only a slight tweaking? 2. Should I just deal with the running rich and spend the $450 elsewhere?
The car is a heads/cam forged internals '99. The previous owner stated that Vette Doctors performed the tune but had no proof. What do you guys think?

If it has already been tuned by a reputable tuner then a follow-up tune will likely only yield marginal results. However, if you have specific issues to address (running rich), then those can be addressed.
The price may be a little high considering the majority of the tuning for the H/C has already been done and you are only looking for a touch up.
Perhaps vette doctors would revise your tune for less $$.

I can only speak for EFILIVE tunes but I'm sure HP is the same--Whenever a tune is downloaded the software will SAVE the VIN # and much of the manufacture details ( trans, eng, plant, etc-) If Vette Dr's did the tune they more than likely still have it and could find it via your VIN #--Many tuners will save both your stock tune and your re-tune indefanately--For some time on their computer and then eventually put them on a disc for safe keeping---I'm sure if they did it they would re-examine your fuel trims and your WOT AFR for a minimal fee ---less than $450

I would have it done at IPS after the catback swap. Since you have no proof that the tune is really good...get it done and have a good baseline. Don't want to take chances with a tune that is off!

^ I kinda agree with the above post Jeremy. I have been thinking about it since we talked yesterday. IPS has proven they can tune a car, I think they have the "world's fastest C6 Z06" record, with 2 cars that have put down over 1100rwhp.
I would just start from square 1 and have them re-tune the car, true, it might not take as much effort as it would be to tune from the stock baseline tune, but I think your car would definately benefit from it though!!

IMO, for folks in the region IPS is the place to go.
