Thread: Gt mods?

so really i didnt understand that. would i need a pcm for all upgrades?

so what kind of pcm would i need for all these upgrades.

It's not really required, but it helps you get the most out of what you've done.

so will i have to get a zzp 1.0 pcm? or have them modify mine?

Dynoing yours is the best option, but getting any upgrade will help. ZZP PCMs are tuned for premium fuel, but you can still put regular in; you just won't get all the benefits.

Heck, even S/C cars can put regular in if they have too, but it should only be used in emergencies when 91+ octane is not available. The savings in the pocket won't mean squat when you damage your engine from running 87 octane. But again, that's for high compression engines like the L67.

Running regular fuel with the PCM will it hurt my car at all or i just won't get all the benefits but it be better then a stock PCM?

I am far from a 3800 expert, but here's a quote from ZZP's website:

"9. What octane do I need to run?

If you have a naturally aspirated vehicle, 91 is recommended. If you have an aftermarket cam, 89 is recommended. Race gas of any type is not recommended. 87 octane will work but performance will suffer some.

If your car is supercharged, or turbo'd premium gas is required. The higher the octane of premmium, the better. Unleaded race gas works well for further improved performance."

You will notice some improvement, as the PCM in its stock configuration is pretty conservative.

ok so i run unleaded gas. and if i put these upgrades on my car i will have to switch to premium gas?

i fill up with premium everytime. with a blower/turbo youll need it to keep from knocking.

"We set our L36 computers up in such a fashion that the more modifications you do the less likely it is that you need to run premium fuel.
Short answer is if you do all those modifications, it is highly likely that you can run 87 octane and actually have better performance versus premium. Vehicles with just a downpipe and air intake will likely require 89 octane and stock vehicles need 91."

you CAN run a lower octane but why would you want to when youre modding your car to be fast?

ok so im just going to do these upgrades.

1. DP 2.5 With high flow cat.
2. Front Power Log
3. SLP 180* Thermo.
4. Cam
5. 1.0 Pcm
6. HV3
7. HVTB

ok well i guess i will just buy a gtp when i get a job. nit nah keep n/a with abunch of non supercharged parts and a gtp with tonz of mods. when i get a gtp i plan to have heads redone and a gen 5 supercharger with a 3.4 pulley with CAI and basic mods.

So your givin up with the GT

no no im going to own two gps. man i wouldnt be putting all this effort and money into my gt for nuttin lol. no i plan on havin two gp so one would be a really fast car (GTP) and (GT) a fast car but not as fast as the gtp. Plus i can have both styles

Don't forget Regal GS, Impala SS and Monte Carlo SS. You want a real sleeper, get a Regal GS and pimp it out...

yea true where i live everyone owns a gp or a impala and most ppl own a monte carlo. I dont care for none of those cars just the fact i think they all look like crap besides the impala but would never would own one just because its chevy. My family is ford and i am the first to have a gm car. but besides that i think on top of my list of getting ported heads. Would ported heads work with stock rockers i know im going to get a agg. cam thats why i want to get heads to so i can knock both of them off my mod list.
