Hey guys I just bought a 05 GTP a month or so ago as my first car that I got with my own money, and I absolutely love it. I have been looking around to try to find the answers to some of my questions, but I have a quite a few that I would love to get answered. Some may be stupid but bear with meAlso, just a few pictures of my new ride Grand Prix - Imgur.
1. I got this car from a dealer who got it from an auction and one of the previous owners did a few mods, but it got repoed from him so I am not 100% sure of all the mods, but from what I can see it has a k&n cold air intake, slp exhaust (all the way up to the headers), and probably a reprogrammed pcm (this is a guess based off the fact that the owner probably wouldnt put all the other money without also reprogramming it, and also it has pretty high mpg [22 city 30+ highway]). According to some research on these mods i would be getting about 35? extra hp (20 from cold air and 10-15 from exhaust). Is this sound about right, me getting 300 hp and 300+ ftlbs torque?
2. How would I go about testing if the pcm is in fact reprogrammed?
3. Even though this is just a daily and the manual says it can run 87, I should run premium(93 where I live) in this right?
4. Could someone explain to me about the grounding problem found in the aftermarket radios? i found one post on it but it wasnt too informative, and I think I have that problem.
5. Would you recommend the use of synthetic oil?
6. I am in desperate need of new tires, so is there a specific all season tire you would recommend? (I live in MI so i have to deal with snow, ice, and rain frequently)
7. What is the best technique to get the best jump? just jam on the gas or hold the brake and rev up the rpms first or????
8. I have cloth seats, and I want to put in the leather as i think they look amazing, would I be able to just drop in some from say a 06 gt or do they not fit that easily?
9. Has anyone painted their calipers? was it a hard process?
10. My low note on my horn is out, and I was wondering if it was a difficult job to put in a new one
11. Have you put in the led interior lights? do they really make a big difference? was it hard?
12. Are there any other inexpensive mods that are really nice? (the leds for ex.)
13. I have read that gtps has the power of a v8 with the mpg of a v6, is this true?
Sorry I know there are alot of questions, but i really appreciate it if you all could help me out!
Once again just saying that I love this car, it is honestly amazing. This is also coming from a guy that was driving a pt cruiser for all of high school (I'm 20 now), its a huge improvement
Thanks in advance!
