2005 Tuner
Hello everyone from below freezing eastern Iowa. A couple of years ago I purchased a 2005 base automatic but have slowly customized some things. Nothing big, CAI and some cosmetic. I installed a throttle controller on my F150 and love it. Looking at options for the 2005 vette, I don't see a lot of options (I believe the 2005 has a slightly different ECU). I am looking for a recommendation on a controller or tuner that I can adjust shift points and throttle response. I am not looking for custom tuning, per say, but would like to know what all of you with 2005 vettes have done. I am a new member so let me know if I've left anything pertinent out (I know you will). BTW, if my wife is looking at this --- i would like to purchase something under $300.00. 
Thank you in advance.

Thank you in advance.I have a 2005 6 speed manual. You have the E40 ecu which was only produced for 2 years. You also have the 4L60E transmission with the factory installed “corvette” servo which already has the best shifting servo. Silverado, Sierra, Suburban, Escalade and Yukon trucks and SUV’s upgrade to the corvette servo. You may not be interested in a custom tune but you’re better off getting a custom tune to max the engine output. However you should consider a full exhaust upgrade before hand to take real advantage of any potential gains. If you don’t want to have to deal with any potential exhaust drone, maybe get a full Z06 exhaust from the manifolds to the NPP mufflers and get an NPP controller. That way you get a nice quiet idle and the full rip roaring sound at full throttle. I don’t believe you’re going to gain any real HP with a $300 option. $200 more dollars and you get a professional tune. Just make sure the shop uses a dynojet dyno and not a mustang dyno.
This may not be the path you wanted or expected but it should be the path you take. You will waste money with a canned box tuner for $300.

Thank you, sir. I already love this forum. Shift points -- check. Happy to learn. I did a muffler delete but that was more for sound (and it sounds awesome). Without really doing anything else to the car, my best option to get rid of the throttle lag would be to get an actual tune to correct that and squeak out what little Hp there is to be had. Do you or anyone else on the forum know of any reputable tune shops in the eastern Iowa area (Iowa city)? Thank you so much for your insight and wisdom.

I just googled dyno tuning shops and came up with this link. There are a list of shops, not many but a couple within driving distance.

Also I still recommend getting a full exhaust upgrade from the engine on back. Mufflers being cutoff will only give you sound, not performance. If you spend money on getting tuned, you’re better off getting headers, x-pipe and muffler upgrades. Speed engineering makes a good full exhaust upgrade. Texas speed is makes a really nice setup but they cost more.
