My SGP experience
I just wanted to clear something up about Kyle. I found an old receipt from my original build and it turns out Kyle did not charge me the Arias or CP piston price for the Wisecos. He did tell me they were better, but he pm'ed telling me that he never had an issue with them and has built cars with over 800whp with those piston. Sorry for the wrongful accusation Kyle, but I jumped to conclusions when Mark told me you were ripping SGP off. I should have looked at my receipt more closely. With that said I would have prefered Arias or CP pistons even though you haven't had any problems with the Wisecos.

1) Shipping car back to SGP with motor issues
2) poor quality work noticed right after pick up
3) unauthorized credit card charges
4) no return calls
5) promises of "I'll give it to you at my cost"
I actually had to get the better business bureau involved and disputed charges with my credit card company as Fraud. I love my Z ( check out my site ) , but I'd sell it before I let SGP touch it again ..it's gone all down hill since Kyle left ..
read the links below for your facts ... familiar reading ???
Original rant after I had enough of the BS
Original Post
Unauthorized credit card charges ( just found the charge on my credit card statement and spent a week trying to get ahold of Mark @ SGP
Mark's response
My response
Upon diagnosing a ton of oil leaks ( SGP never test drove the car prior to pick up ), I drove the Z back to Delaware from Texas, had to put 1/2 oil in the motor in Virginia.
I find later JB weld on my block ???? WTF ????

I have been planning this thread since last year when you made your thread on tt.net.
thanks for posting. I am sorry you dealt with the same BS as me!
Gman,
I am sorry to hear about your experience, and I am not taking sides but, I just wanted to say that I sent my car to SGP Racing based on old posts that you and a few others put up. I even sent you 1 or 2 pm’s way back and asked you a few questions about the FCON and you had nothing but great things to say about Mark and SGP. I am sorry that you are going through all this, but the story sounded a little different the last time it was told.

I have had nothing but great experiences with Mark, and SGP and would never have found them if it was not for you and others who posted about them. So now, I have been trying to figure out how this all went so side ways for you, when Mark seems to go above and beyond for all of his customers.

I tried to find my old post where I posted that my a/f at idle was in the 13's, but I couldn't find it. I am gonna search more.
Here's something from May 2006 where I posted about a rich condition.

its not like he got a raw deal and posted the next day, the man has been waiting for 1 year to tell his story. Sharif and Sam know his story, two of top Z/G tuners/installers on this country including i would say maybe 5 more guys.
I didn't need to see Mark's post to believe if Gman is telling the truth or not.. everyone knows what Gman has been through.. we just didn't know who was behind it.

"your 43 post count gives you some leeway in this, but people wouldn't be backing up Gman unless he was a established member. I for one, don't know the guy personally, but his conduct on the board has been great, and I would give him the benefit. SGP has had problems in the past."
motormouth are you serious? why does my post count matter whatsoever? that's definitely the nerdiest thing i've ever heard in my life man...everyone here is giving opinions so why can't i? i have been the only on really standing up for the side of this story that wasn't there because of my first-hand accounts with Mark, i haven't said anything bad about Gman at all and have supported his story and hoped for a resolve very soon. every shop has had problems, mark, sam, sharif, gimme a break if you think others haven't. i've been following gman's posts for a while cuz he was one of the few back in 2005 that was doing a built motor and i looked at his project for support. either way guys, i said i'm here to view now that mark has posted back, so leave me outta this
Here's another post about my idle although I didn't mention anything about running rich, but just to clarify my a/f was in the low to mid 10's. Although safer I don't need to be running that rich considering all my mods and built motor. Running 11:5 is safe enough with everything I have.

i know the shape his car was in when it came to ATL... i heard the horror stories... nothing about his story has changed since that time last year... i'm glad mark offered his side of the story, but nothing will sway my opinion when i witnessed the atrocity first hand...
I found it. These were post April of last year.

Guys I am not making this chit up. I have no reason to lie. The only thing I might have posted incorrectly are the actual dates of events, but that's because I am going off my memory for chit that happened over a year ago.

YEP , Mark was stupified when he saw the picture. I had oil gushing out of the area and even though Mark offerred to fly to Philly to fix the issue ( said he was tuning a car in NJ soon ) , I just wasn't too comfortable with that.
I ended up paying a local guy to fix it and thank god the motor didn't have to come out. Still more money out of pocket to fix an oil leak the right way.

This may be true, but I am sure that you have heard of the countless cars that Mark has worked on from other shops all around the country as well!

just because a murderer kills a man who was going to kill someone else doesn't make him any less of a murderer
Kind of off topic, but.......Gman, how did you determine it was a blown coil? Was it hesitating real bad? Im having issues right now and I think it might be a blown coil. Also, how did you determine, which coil was blown? Thanx.
