Booher, I seem to be right behind you on this header project! However, I can use my wife's car if need be.
Sorry don't mean to hijack the thread, but I'm in almost the same boat as Booher.
However, I have a few questions which may help others new to this HP Tuner tuning.
I took my car to a Performance shop to have the AWE and Kooks connected.
I asked him if he could tune the car also since I just installed the headers, but no CEL yet.
He mentioned he could, but I needed to purchase 3 credits...I know nothing about this HP Tuner stuff and what these credits mean/do.
He said the car is going to be running lean, so do not go WOT until it is tuned, my engine will not appreciate it and valves may start to melt.
Is this true? Do headers make the system run lean?
Another tuner told me this, "Your engine won't be lean at all. Fuel mixture is largely dictated by the MAF, all air flows through it. Any performance improvements from the headers will result in more air flow which will result in more fuel".
So who's telling the truth here?
I feel like I'm watching the news!
Anyway, how is it that Booher needs 4 credits or 5 and I only need 3?
I don't have the wide band sensor, is that the reason why?
I'm a manual as well, so no tranny tuning.
