16/26 on a stock 99 gtp!? i suppose its possible but iv never heard of it, unless something is functioning improperly. I get 19/28mpg with my mods. there are many people complaining of gas mileage on their cars....go look at some of the Gas Mileage threads.....

Yea i figured a tuner would be key. I wonder if i can create two BIN's one for speed (1/4 mile) and one for gas. I suppose you could, there is also something out there called a "happy knob" that you may want to look into to see if it is for you or not. Do a search....

Since i would have an IC meth would be pointless as far as i know, wouldn't it only raise my octane?

looking at RR's, maybe this would get me closer to my goal withouht the significant decrease in gas mileage. yes it would help as they reduce friction......actual gains depend on what else you are doing with the heads/cam and what ratio RR's you might want.



-I understand about the CR just don't know which ratio would be optimum for my build. Yes it has to be high because i'm looking to run a S/C setup but higher then 9.4? You need the lower compression ratio for higher amounts of boost, not a higher compression ratio....

-Theoretically ported heads, like any ported object, should flow better but are our cars restrictive in this area? Does the lim usually match up well with the Heads?

-SFPHQ bullet proof shafts? Ill have to look around for these. South Florida Pulley Headquarters. I have been looking for the best cv axles around and these seem to be at the top of the list. I dont know if anyone on here actually runs these or not?
-Yea i should have noted the MSD coils would only be for look. I have not seen any test results saying they are worse so basically they would just look cool

-O0o how did i forget fuel pump! lol. Not sure how big of injectors i want to go, i want just big enough so i don't go lean at WOT. When you are scanning you will know when you are maximizing out the injector sizes that you currently have. Stock will not make it to your goal, but the question is, how much do you want to upgrade?

Thanks again!
No Problem..... I can see having gas mileage not that effected on the 3.4 pulley because it is still mostly stock with a few flow upgrades and you are not pushing the limits of anything. Also at this point the PCM is reprogrammed to optimize things that are not being taken full advantage of from the factory. After this point HP and speed comes with a price, as you have already upgraded flow mods to a great degree and increased efficiency of the computer. IMO........after this point when you start doing head work, install a cam of any size, up the compression ratio, and start changing the PCM program to get maximum HP out of it you are going to start losing MPG's fast and pushing the reliability of your vehicle drive train.
