Re: Which Performance Chip do you have?
 

After my porting I was running on a stock chip. It ran a lot better but less than I expected. I bought a new chip with the fuel correction from Marc Hibieck and what a difference. Now it really runs strong.

LPE chip with Mark Haibeck attention to detail - he is rare.

i did my own on all my Zee's. also did Craigs427 for him as well. work good. loosely based off Mark's. really only so much one can to do these especially if the engines' stock. all the R&D has long been done. one thing i do different than most is i stagger when the cooling fans come on by 5°. not as much draw on the electrical system all at one time. not right or wrong but just made sense to me to do it that way for obvious reason.

Just got my Haibeck reprogramed prom back. So far its just as he said it would be. I see a much smoother off idle throttle response & an overall better functioning engine. The power always on is something I thought I wouldnt really like, but I do. The running temps are about 10-15* cooler and the knock is gone under throttle when I take off and the engine is hot. Funny thing is I thought I heard it ping a bit in second under harder than normal acceleration the other day. I am going to fill up with a different brand of premium next time and see how it does.

Does adding over the counter fuel octane booster make a difference? Anyone use a product like 104+ or similar? Comment on what you used & like.

I try to always get BP premium - never use the 104 see no need to -- never had ping even with lesser grades of Prem. But I have had a custom chip within the first month of ownership. Fans on early and no cags is great. Much better overall performance as well --even more than just a seat in the pants thing really could tell a big diff.

SGC / Mark Haibeck Chip :dancing

Haibeck is the man..... Excuse the term, but my Z runs like a RAPED APE and I love it. :dancing

Re: Which Performance Chip do you have?
 

Marc H for me. Great reputation, had what features I wanted, and only a couple miles from my place of work (handy to have a GURU so...handy!)

Z-Industries -- but I have no feedback to offer yet, since the secondaries aren't working :-D

Edit: OK, secondaries are working, car runs well, but I have nothing to compare to!
