H2 Passion
It is way cheaper and not really complicated. Intake took 30 min., throttle body at same time took 15 min., programer took 10 min., and exhaust took 1.5 hours. Header pro tells me about 2 to 3 hours. It is all he does is specialize in header application and install. Alot of the other I'll do myself. If You put it all together I guess a good 8 hours on it all. You let the pro do the work just tell him what you want. It will take a couple of months maybe not (could be by end of Dec.) to finish and then I'll get it dinoed. Nothing is as good as SC but I'm estimating less than 2 grand and pro's here are estimatimg going from 325 HP to 425 or 450 HP and they are leaning heavily towards the 450hp and a vast torque improvement, no up and down shifting anymore. These are estimates based on manufacturer HP gain and we shaved it down by rounding down numbers from factory. I feel confident I will get it in around 2 grand. Dino only rely knows hp and torque. In the first 4 items I have spent $960 and it made it feel like I was driving a different H2. Friends who had been in it before could not believe how it put them back in the seat. Out of the remaining the real help will come from the headers.

I really would like some input on the MAF, coolant throttle body bypass, and the 160 degree thermo.

I know electric fans will help as I noticed a big difference on My silverado when I put it on this past summer.

Guys jump in here and help me with the questions I have on MAF, Throttle body bypass and 160 stat. I know someone has had experience with those things.
Thanks
